Plant Structure Review

Which of the following describes carnivorous plants such as the pitcher plant?

• grow on other plants and catch falling water and debris
• live in nutrient poor areas with little rain fall so they have shallow roots to soak up water immediately
• climb up other plants or objects in order to reach sunlight
• live in areas with nitrogen-poor soil so they rely on capturing insects for their nitrogen supply
• attach to a host to obtain nutrients and rarely perform photosynthesis for themselves

Which of the following is representing the apical meristem?

• (a)
• (b)
• (c)
• (d)
• the apical meristem is not pictured

Collenchyma cells are

• Cells that make up the gritty texture in pears
• Cells that support non-growing regions
• Cells that make up the stringy strands in celery
• Cells that conduct water
• Cells that perform photosynthesis

Sclerids are cells

• Responsible for photosynthesis and food storage
• Responsible for gritty texture in pears
• Responsible for controlling the flow of sap
• Responsible for moving water up
• Responsible for supporting the growing regions of plants

Identify structure 'C' in the cross section.

• Vascular cylinder
• Cortex
• Exodermis
• Phloem
• Epidermis

Which of the following best describes xylem?

• Tissue located on the outer surfaces of plants. Responsible for protecting the plant.
• Vascular tissue responsible for conducting sugars as sap. Alive when functioning.
• Tissue responsible for the growth of the plant. Only place where mitosis occurs.
• Metabolic tissue responsible for carrying out photosynthesis and storing food.
• Vascular tissue responsible for carrying water and minerals throughout plant. Dead when functioning.

Identify structure 'B' in the cross section.

• Vascular tissue
• Epidermis
• Ground tissue
• Collenchyma cells
• Sclerids

Dermal tissue could be described as the

• sap carrying tissue
• water carrying tissue
• metabolic tissue of the plant
• skin of the plant
• growing region of the plant

Which of the following describes the meristematic tissue of plants?

• conducts water
• growing regions
• metabolic functions
• conducts sap
• outer protective layer

Which of the following describes the function of collenchyma cells?

• perform photosynthesis
• store food
• support the growing parts of plants
• maintain metabolic functions
• support the non-growing parts of plants
