Answer:

Do you think there is a quantitative relationship between transpiration rate and number or size of leaves on the stem? Explain your answer. Yes, the more leaves a plant has, means more stomata will be available for transpiration. ... Without light to facilitate photosynthesis, most plants close their stomata at night.

Answer: The attachment listed some cell organelles,although there isn't a specific question on then but am going to be defining each of them and state their functions as well.

1. The Nucleus; The is command centre of the cell, it is made up of nuleolus, chromosomes, nucleoplasm,nuclear envelope and nuclear lamina.

it contains the genetic/hereditary materials that the cell is made up of.

The Nucleus plays a great role in the control of growth and development of the cell.

The nucleus also coordinates some of the the activities of the cell like cell division and protein synthesis.

2. Cytoplasm; The cytoplasm is one of the cell organelles,it is the liquid portion of the cell,it consists of cell contents between the plasma and the cell membrane. The fluid cytoplasmic material is where many cell organelles are found/suspended fluid. Most activities carried out by the cell occurs in the cytoplasm.

3. Endoplasmic Reticulum; The Endoplasmic Reticulum is one of the cell organelles that have the structure of a network of flattened sacs and tubules and play a crucial role in plant and animal cell. Rough endoplasmic reticulum has ribosomes attached to the cytoplasmic side of the membrane and the smooth endoplasmic reticulum lacks attached ribosomes in them thus giving it the smooth appearance.

The Endoplasmic Reticulum functions in the production, processing, and transport of proteins and in and out of the cell and also the production of lipids.

4. Golgi Body; One of the plant organelles that plays a role in the sorting and organizing the proteins produced and processed by the Endoplasmic Reticulum. these proteins are sorted and packed in vessicles to be used by the body.

5. Mitochondria; (a double membrane organelle). It is otherwise known as the powerhouse of the cell,it produce/generate energy in the form of ATP needed for cellular respiration. These energy produced is used for other cellular metabolic activities.

6. Lysosome (Animal) Chloroplast (Plant); Lysosomes are found in most animal cells, they function by digesting good and garbage,they contains acids that aids this function in the stomach of the cell and when the lysosome is diseased or explodes,the cell stops functioning.

The Chloroplast on the other hand is found in the cells of plants and algae,they play a crucial broke in photosynthesis by capturing the energy from the sun and turning the captured energy into usable forms like sugar,glucose and other organic molecules.

7. Cell Membrane; The cell membrane is the cell organelle that forms a boundary between the cell and the sorounding environment.

The cell membrane as well controls the movement of cellular materials in and out of the cell.

8. Nucleolus; The nucleolus is one of the cell organelles where ribosomes are made. The ribosomes are small grain-shaped organelles that make protein and they are found in the surface of rough Endoplasmic Reticulum. Nucleolus are small and round in structure and are found in the nucleus,

9. Vacoule (Plant Cells) Centrioles (Animal Cells); The vacoule is a storage chamber(reservoir) for wanted and unwanted materials in the cell, the vacoule is found within the cytoplasm and it is enclosed by a membrane that typically contains fluid.

The centrioles on the part of the animal cell is a cell organelle that has a structure of a two hollow cylinders,ring of microtubules next to each other(the centrosome).the centrioles are located just outside the nucleus of the cell.

Centrioles function by producing the mitotic spindles for cell division, and also assisting to pull chromosome pairs apart to opposite end of the cell during cell division.

10. Cell Wall; A protective semi permeable rigid outer layer of nonliving material that surrounds the cells of plants and some other organisms.

The cell wall houses the organelles of the plant cell.

The cell wall functions by giving the cell strength and structure,it's semi permeable nature filters and selectively allows certain materials in and out of the cell.

Without elephants, some of the grasslands in Africa would eventually become thickets or forests because elephants weed out trees
rewona [7]

Answer:

Without elephants, some of the grasslands in Africa would eventually become thickets or forests because elephants weed out trees and shrubs. Even though elephants make up a small percentage of the animals living on the grassland, the grassland would eventually cease to exist without them. In this community, elephants are <u>keystone species</u>.

Elephants are often called “keystone species” because of their unique role in providing vital services to an ecosystem in relation to their abundance.

Explanation:

Elephants play a very important role in maintaining the biodiversity of the ecosystems in which they live. During the dry season, elephants use their tusks to dig for water. This not only allows the elephants to survive in dry environments and when droughts strike, but also provides water for other animals that share harsh habitats.

Elephants eat some trees and create gaps in the vegetation. These allow new plants to grow and create pathways for other smaller animals to use. They are also agent of seed dispersal of trees and in fact some species of trees rely entirely upon elephants for seed dispersal.

Elephants feed on tree sprouts and shrubs in savannahs. They help keep the plains open and able to support the plains game that inhabit these ecosystems.

Elephants also leave a dung that is full of seeds from the many plants they eat. When this dung is deposited, the seeds are sown and grow into new grasses, bushes and trees, thereby boosting the proliferation organisms in the savannah ecosystem.
