This organ provides more than one function to the plant. Which of the following is a function of this organ illustrated in the picture?

Question 6 options:

Anchors the plant in the soil


Absorbs oxygen from the soil


Transports carbon dioxide to the soil


Releases water into the soil

Answer: Microtubules provide a rigid structure, or cytoskeleton. or produce oxygen and consume carbon dioxide

Explanation:

Most cells contain microtubules, which are tubelike structures formed by tubulin proteins. Microtubules appear and disappear as needed in many algae.

Microtubules are important cytoskeleton components. They are found in all eukaryotic cells and play roles in mitosis, cell motility, intracellular transport, and cell shape maintenance.

Microtubules are made up of alpha- and beta-tubulin subunits that have been assembled into linear protofilaments.

Microtubules, along with intermediate filaments and microfilaments, are components of the cell skeleton that determine cell shape.

Microtubules play a variety of roles, including mitotic spindle assembly in dividing cells and axon extension in neurons.

Microtubules, which are tubelike structures formed by tubulin proteins, are found in the majority of cells. In many algae, microtubules appear and disappear as needed.

Microtubules provide a rigid structure, or cytoskeleton, in the cell that aids in cell shape determination and maintenance, especially in species lacking cell walls.

Thus, this way, the shape of an algae cell help it function.

There are two main types of fibre; collagen, and elastin and fibronectin.

There are two main types of fibre- collagen, and elastin and fibronectin are commonly found in extracellular matrix.

A large network of proteins and other molecules that surround, support, and give structure to cells and tissues in the body. The extracellular matrix helps cells attach to, and communicate with, nearby cells.

The extracellular matrix (ECM) is the non-cellular component present within all tissues and organs, and provides not only essential physical scaffolding for the cellular constituents but also initiates crucial biochemical and biomechanical.

The extracellular matrix helps cells attach to, and communicate with, nearby cells, and plays an important role in cell growth, cell movement, and other cell functions.

According to cladogram, two species that are more closely related are worms and ants. The correct answer is worms and ants and they both are usually found in the herbivores food.

It is the category in which animals feed on plants and the food based on plants.

Most ants  are  not eating  worms but they may eat dead worms. Ants harm on worms by attacking the worms' food and To protect worms from these types of ants by raising  the level of moisture in worm farm by re-wetting system regularly.

Sometimes, ants make way to compost bins to seek vegetables and fruit scraps meant for worms. This is the only kind of harm inflicted by ants on worms.

The specie will avoid extinction which have a large amount of food in that environment probably specie B.

That specie will most likely be able to avoid extinction which receives more amount of desired food because food is the main source on which all living organism can survive.

If desired food is not available for the organism, its population size decreases and reaches to the point of extinction so we can conclude that the specie will avoid extinction which have a large amount of food in that environment.

It is possible to determine population change by adding the births and immigrants then subtracting the deaths and emigrants. These phenomena modified the size of a population.

A population can be defined as a group of individuals of the same species living in a given area.

The forces that alter the growth/size of a population include birth rate, immigration, death rate, and emigration.

The birth rate and immigration positively impact the size of a population, whereas death rate and emigration negatively impact the population.

Cellular respiration is a series of reactions by which aerobic cells produce ATP (energy) by using the energy from foods and oxygen.

Cellular respiration has three main steps: glycolysis, the citric acid cycle and oxidative phosphorylation.

Glycolysis occurs in the cytoplasm, whereas the acid citric cycle and oxidative phosphorylation occur in the mitochondria.

Oligosaccharides are complex carbohydrates that have 3 to 10 simple sugar units and cannot be broken down by the body's digestive enzymes. They are complex carbohydrates.

Oligosaccharides are complex carbohydrates composed of three or more monosaccharides (e.g., glucose and fructose) or the union of two or more disaccharides (e.g., lactose).

Humans cannot digest these oligosaccharides because we don't have digestive enzymes such as ⍺-galactosidase, thereby they cannot be hydrolyzed.

Complex carbohydrates are in turn long chains (either branched or unbranched) of monosaccharides linked by glycosidic bonds.

A well-known example of complex carbohydrates (polysaccharides) is starch, which is composed of many subunits of glucose.

Enzymes that break down complex carbohydrates must have the ability to break glycosidic bonds.

Explanation:

Pollen is produced within the anthers (microsporangia or pollen sacs) of the flower. During its development from an undifferentiated mound of cells (anther primordium) the anther forms two general groups of cells. The reproductive or sporogenous cells give rise to the microspores and are formed from cells located centrally within the developing anther. The non-reproductive cells form discrete anther tissues layers and include the epidermal, cortical and tapetal cell layers surrounding the sporogenous cells. The tapetum which is the innermost layer of the pollen sac plays a dominant role particularly during the microspore stage. For example, many male sterile mutations affect tapetal cell functions and development is often arrested during the microspore stage.

Microsporogenesis and microgametogenesis

Two distinct and successive developmental phases, microsporogenesis and microgametogenesis, lead to the production of the mature microgametophytes.

dev

Microsporogenesis comprises the events which lead to the formation of the haploid unicellular microspores. During microsporogenesis the diploid sporogenous cells differentiate as microsporocytes (pollen mother cells or meiocytes) which divide by meiosis to form four haploid microspores. Each diploid meiocyte gives rise to a tetrad of four haploid microspores and microsporogenesis is complete with the formation of distinct single-celled haploid microspores.

Microgametogenesis comprises events which lead to the progressive development of the unicellular microspores into mature microgametophytes containing the gametes. This phase begins with the expansion of the microspore which is commonly associated with the formation of a single large vacuole. Vacuolation is accompanied by the displacement of the microspore nucleus to an eccentric position against the microspore wall. In this position the nucleus undergoes first pollen mitosis (pollen mitosis I) which results in the formation of two unequal cells, a large vegetative cell and a small generative cell each containing a haploid nucleus. The generative cell subsequently detaches from the pollen grain wall and is engulfed by the vegetative cell forming a unique 'cell within a cell' structure. The engulfed generative cell divides once more by mitosis (pollen mitosis II) to form the two sperm cells completely enclosed within the vegetative cell cytoplasm either before pollen is shed (tricellular pollen) or within the pollen tube (bicellular
