Guard cells are found in the epidermis of the leaves, whereas the tracheid, vessel element, companion cell, and sieve tube element are found in the xylem and phloem tissues of the plant’s vascular system.

C. guard cell

New cells that are produced under mitosis are formed in the meristems of a plant. Only the plant’s meristematic tissue are produced via mitosis.

A. I only

Phloem, cork, and cork cambium form the bark of a tree.

E. I, II, and III

The combined forces of root pressure, capillary action, and transpiration, which includes evaporation, are all involved in the movement of water through the plant’s vascular system. Meristems are involved in the reproduction of new cells in the plant.

D. meristems

A heartwood contains a non-functioning xylem.

A. heartwood

Palisade mesophyll is a layer of mesophyll cells found under the epidermis. They are responsible for absorbing the light needed for photosynthesis.

E. mesophyll tissue

Casparian strips aid in the one-way or upward movement of water molecules in the vascular cylinder of the roots. Since the strips have a hydrophobic feature that gives a wax-like texture in the cell walls of the roots, it prevents back flow by helping contain the water inside the vascular cylinder.

D. Casparian strip

Monocots, such as grasses have fibrous roots that helps the topsoil to be intact during a heavy rain.

D. grass

The table shows that the bottom surface of the leaves in all the plant samples contains more number of stomata compared to its top surface.

B. Plants have fewer stomata on the top side of their leaves than on the bottom side.

Guard cells are usually triggering the stomata to open during the day when there is a huge amount of sunlight. During the night, the stomata has a tendency to close since there is a lack of light.

D. stay open during daylight hours
