Understanding Plant Parts

This video tutorial from Mumu Math and Science explores the parts of a plant, focusing on roots, stems, and leaves. It explains the functions and types of roots, including tap and fibrous root systems, and describes the structure of roots with root caps and root hairs. The video also covers the roles of stems in support, transportation, and storage, distinguishing between herbaceous and woody stems. Finally, it discusses the structure and function of leaves, emphasizing photosynthesis and the role of chlorophyll, stomata, and vascular tissues.

What is the primary function of a plant's roots?

• To produce food through photosynthesis

• To anchor the plant and absorb water and nutrients

• To store food for the plant

• To transport water from leaves to roots

Which type of root system consists of a long, thick main root?

• Tap root system

• Fibrous root system

• Adventitious root system

• Lateral root system

What is the role of xylem in a plant?

• To protect the plant from external damage

• To store nutrients for future use

• To transport water from roots to the rest of the plant

• To transport food from leaves to roots

What is the function of the cambium in woody stems?

• To transport nutrients to the leaves

• To protect the plant from pests

• To store water for the plant

• To produce new xylem and phloem

Which type of stem is soft and flexible?

• Fibrous stem

• Tap stem

• Herbaceous stem

• Woody stem

What is the primary role of leaves in a plant?

• To absorb water from the soil

• To capture sunlight and perform photosynthesis

• To protect the plant from herbivores

• To transport nutrients to the roots

What is the function of the cuticle on a leaf?

• To absorb sunlight for photosynthesis

• To store carbon dioxide

• To prevent water loss

• To transport nutrients to the stem

What are stomata responsible for in a leaf?

• Protecting the leaf from damage

• Storing nutrients

• Exchanging gases like carbon dioxide and oxygen

• Transporting water from roots

During photosynthesis, what is produced from carbon dioxide and water?

• Nitrogen and glucose

• Oxygen and sugar

• Carbon monoxide and starch

• Water and protein

What role does chlorophyll play in photosynthesis?

• It absorbs water from the soil

• It captures sunlight energy

• It transports nutrients to the roots

• It stores oxygen for the plant
