Botany and Plant Science Questions
Which of the following is a type of plant tissue?
-
Parenchyma
-
Collenchyma
-
Sclerenchyma
-
All of the above
D
Correct answer
Explanation
Plant tissues are groups of cells that perform specific functions for the plant. Parenchyma is a type of tissue that is found in many parts of the plant and performs a variety of functions, including photosynthesis, storage, and support. Collenchyma is a type of tissue that provides support for the plant, and sclerenchyma is a type of tissue that provides strength for the plant.
Which of the following is a type of plant organ system?
-
Root system
-
Stem system
-
Leaf system
-
All of the above
D
Correct answer
Explanation
Plant organ systems are groups of organs that work together to perform a specific function for the plant. The root system absorbs water and nutrients from the soil, the stem system transports water and nutrients throughout the plant, and the leaf system photosynthesizes and produces food for the plant.

-
Taproot system
-
Fibrous root system
-
Adventitious root system
-
Prop root system

What is the term for the specialized structure in angiosperms that produces ovules?
-
Stamen
-
Pistil
-
Petal
-
Sepal
B
Correct answer
Explanation
