The image shows a magnified view of a leaf's surface with the stomata visible. What’s the significance of these structures in th

e process of photosynthesis?
They’re the sites of maximum photosynthesizing activity because of the concentration of chloroplasts.
They’re the storage sites of glucose, which is produced during the process of photosynthesis.
They absorb water vapor from the atmosphere, providing water to the plant for photosynthesis.
They allow the exchange of gases between cells in the leaf and the external environment.
They allow light energy to enter the leaf, which is vital for the process of photosynthesis.

The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.

Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.

The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.

Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.

Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.

How does the human brain store and retrieve memories?
krek1111 [17]

Answer: After consolidation, long-term memories are stored throughout the brain as groups of neurons that are primed to fire together in the same pattern that created the original experience, and each component of a memory is stored in the brain area that initiated it (e.g. groups of neurons in the visual cortex store a sight, neurons in the amygdala store the associated emotion, etc).

The Equator line does not pass through the north and south poles. This line divides the Earth's planet into two hemispheres.

The Equator can be defined as an invisible line located at the center of the Earth (0 degrees latitude).

This invisible line (Equator) divides the Earth into two hemispheres: the northern hemisphere and the southern hemisphere.

The Equator is a circle of latitude, and the distance of this imaginary line is approximately 40,000 km in circumference.

9. Which structure helps animal cells maintain their shape?
ludmilkaskok [199]

Answer:

<em><u>D. Cytoskeleton</u></em>

Explanation:

It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.

The Cell Walls are only in plant cells so that won't work.  So, A wouldn't work.

Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.

Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either

The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.
