Question 1 of 26

1

Which of the following statements is FALSE regarding plant meristems?

Select one of the following:

Apical meristems are found in shoot tips, root tips and buds and are responsible for the increase in the length of these plant parts
Lateral meristem, sometimes referred to as the cambium, is responsible for the increase in stem and root diameter or thickness

Explanation

Question 5 of 26

1

Buds are meristematic structures along the stem that are composed of compressed, immature, leafy shoots, flowers or both. They may be dormant for a portion of the year of for many years before they become active.

Question 6 of 26

Explanation

Question 7 of 26

1

Which of the following statements is FALSE regarding leaves?

Select one of the following:

The epidermis is a thin protective layer of cells on the upper and lower surfaces.
Immediately under the upper epidermis are densely packed cells that contain chlorophyll, the green pigment necessary in photosynthesis.
Inside the lower epidermis are widely spaced cells that permit free movement of water vapor, carbon dioxide and oxygen in and out of the leaves through stomata.
Pairs of specialized cells, termed plastid cells, control the opening and closing of stomata.
Guard cells respond to light so that stomata are normally open in daylight and closed in the dark
