The photograph to the right shows an area of the root where cell division takes place. Cells that are undifferentiated and increase the length of the root are found in the A. epithelium B. apical meristem C. dermal tissue D. ground tissue

The area marked A is home to epidermal cells. Epidermal cells found on the top of a leaf….

A. tend to be covered with thick, waxy layers B. Tend to contain many chloroplasts C. Tend to contain pores called stomata D. Tend to have thin, hair-like extensions

The areas marked C and D are home to root hair cells. Root hair cells….

A. absorb water and nutrients from the soil B. are coated with a thick, woody layer C. contain many chloroplasts D. tend to live for a long time

The flower of a plant usually contains two types of specialized cells, vegetative cells and germ cells. Germ cells… A. tend to contain pits in their cell walls B. die when they are mature C. produce gametes such as egg cells D. do not contain any water

The diagram below represents root epidermal cells. The major function of the structures labeled X is to A. Increase the surface area for absorption of water B. Absorb complex food particles for transport to the leaves C. Transport carbon dioxide from the roots to the leaves D. Move food particles into the phloem

The underside of a leaf contains tiny pores called stomata. These pores lie next to specialized guard cells. The structure of the specialized guard cells and the stomata do not help the plant to….

A. release water during transpiration B. capture pollen for sexual reproduction C. absorb carbon dioxide for photosynthesis D. enable the flow of nutrients from roots to the rest of the plant

The leaves of a plant are dotted with openings known as stomata. When open, stomata allow the plant to exchange gases and allow moisture to evaporate. This helps draw water from the roots up into the plant. These activities allow the plant to… A. maintain homeostasis B. decompose organic matter C. produce light energy D. synthesize minerals

An acacia tree has many compound green leaves. These leaves grow because the tree receives necessary minerals collected by….

The integumentary system B. The excretory system C. The vascular system D. The reproductive system

A horsetail opened stomata in its leaves to release oxygen. The horsetail then took in carbon dioxide to create energy.
