Plant Anatomy Quiz Ch 30

What are the two main organ systems in a vascular plant?

• Root system and shoot system

• Circulatory system and respiratory system

• Digestive system and nervous system

• Skeletal system and muscular system

Answer explanation

The two main organ systems in a vascular plant are the root system and shoot system, responsible for absorption of water and nutrients, and photosynthesis and reproduction, respectively.

Match the following plant functions with their descriptions:

• Function that serves as a barrier against physical damage and pathogens

• Transporting water and nutrients

• Function that helps in maintaining the shape and rigidity of the plant

• Providing structural support

• Function that converts light energy into chemical energy

• Producing food through photosynthesis

• Function primarily involved in the movement of essential substances throughout the plant body

• Protecting the plant from external factors

Name the three tissue systems found in a plant stem.

• Dermal, Vascular, and Ground tissues

• Epidermal, Mesophyll, and Endodermal tissues

• Xylem, Phloem, and Cambium tissues

• Root, Stem, and Leaf tissues

Answer explanation

The three tissue systems found in a plant stem are Dermal, Vascular, and Ground tissues, which are responsible for protection, transport, and storage functions respectively.

Match the following functions of plant parts with their correct descriptions:

• Function of stems in some plants

• To absorb water and nutrients

• Function of the trunk in trees

• To produce flowers

• Main function of roots

• To produce fruits

• Function of flowers after pollination

• To provide support to leaves

Match the following root systems with their descriptions.

• Consists of thin, moderately branching roots growing from the stem

• Taproot and adventitious root

• Roots that grow from any part of the plant other than the roots

• Adventitious root and aerial root

• Consists of a main root that grows down vertically, and from which many smaller lateral roots arise

• Fibrous root and aerial root

• Consists of a main root that grows down vertically, and roots that grow from other parts of the plant

• Taproot and fibrous root

What is the purpose of a root cap?

• To absorb nutrients from the soil

• To protect the root tip and assist in root growth

• To conduct photosynthesis

• To support the plant in the soil

Answer explanation

The purpose of a root cap is to protect the root tip and assist in root growth.

What are the three main zones of a root tip?

• Zone of cell division, zone of elongation, zone of maturation

• Zone of root hairs, zone of absorption, zone of storage

• Zone of photosynthesis, zone of respiration, zone of transpiration

• Zone of differentiation, zone of elongation, zone of root cap

Answer explanation

The three main zones of a root tip are the zone of cell division, zone of elongation, and zone of maturation.

What is the main function of leaves in a plant?

• Photosynthesis

• Supporting the plant structure

• Absorbing nutrients from the soil

• Reproduction

Answer explanation

The main function of leaves in a plant is photosynthesis, where they convert sunlight into energy for the plant.

What is the outermost cell layer of a leaf called?

• Epidermis

• Mesophyll

• Cuticle

• Stomata

Answer explanation

The outermost cell layer of a leaf is called the Epidermis.

What are the two main components of leaf tissue?

• Xylem and Phloem

• Epidermis and Mesophyll

• Stomata and Guard Cells

• Roots and Shoots

Answer explanation

The two main components of leaf tissue are the Epidermis and Mesophyll, which are responsible for protection and photosynthesis, respectively.
