Questions and Answers

Match the components required for photosynthesis with their roles:

Light Energy = Powers the conversion of carbon dioxide and water into glucose Chlorophyll = Absorbs and stores light energy in chloroplasts Carbon Dioxide = Raw material that combines with water to form glucose Water = Raw material absorbed from the soil and transported to leaves

Match the terms with their descriptions related to the locations in a plant where photosynthesis occurs:

Leaves = Primary site where photosynthesis takes place Chloroplasts = Organelles within leaf cells that contain chlorophyll and facilitate photosynthesis Stomata = Pores on the leaf surface through which carbon dioxide enters Root hairs = Absorb water from the soil, which is then transported to the leaves

Match the steps of the photosynthetic process with their outcomes:

Absorption of Light Energy = Conversion of light energy into chemical energy stored as glucose Intake of Carbon Dioxide = Combination with water to produce glucose in chloroplasts Absorption of Water = Transport to leaves, where it participates in glucose formation Production of Glucose = Use of energy stored in chloroplasts for plant nourishment

Match the roles of the following plant structures in the transport of essential elements for photosynthesis:

Root Hairs = Absorb water from the soil Stem = Transports water from the roots to the leaves Stomata = Allow carbon dioxide to enter the leaves from the atmosphere Chloroplasts = Use water and carbon dioxide from the leaves to produce glucose Signup and view all the answers

Study Notes

All living things need food for survival.
Plants produce their own food through photosynthesis, unlike humans and animals.
Only green plants are capable of photosynthesis.
The word "photosynthesis" combines "photo," meaning light, and "synthesis," meaning making or putting together.
During photosynthesis, leaves capture sunlight to create sugar molecules like starch.
Light energy is converted into chemical energy and stored in starch molecules.

Requirements for Photosynthesis

Plants need four essential elements: light energy, chlorophyll, carbon dioxide, and water.
Photosynthesis can occur with both sunlight and artificial light sources like lamps.
Chlorophyll, a green pigment, is located in chloroplasts within leaf cells.
Chloroplasts are responsible for absorbing and storing light energy.
Stored light energy is used in the food manufacturing process.
Carbon dioxide and water act as raw materials for photosynthesis.
Plants extract carbon dioxide from the air through stomata, pores on leaf surfaces.
Carbon dioxide travels from stomata to chloroplasts to combine with water and form glucose.
Combining carbon dioxide and water uses the energy stored in the chloroplasts.
Plants absorb water from the soil via root hairs.
Water is transported from the roots to the leaves through the stem.

Equation for Photosynthesis

Glucose produced during photosynthesis is transported to different parts of the plant through special tubes.
The process involves plants using carbon dioxide, water, and light energy to produce glucose and oxygen.

Summary of Photosynthesis

Green plants create their own food via photosynthesis.
Light energy trapped by leaves is converted to chemical energy during photosynthesis.
Photosynthesis relies on light energy, chlorophyll, carbon dioxide, and water.
Chloroplasts contain chlorophyll, which absorbs and stores light energy for food production.
Carbon dioxide enters leaves through stomata from the atmosphere.
Carbon dioxide reaches chloroplasts, combines with water, and forms glucose, utilizing stored energy.
Plants absorb water from the soil through root hairs, then transport it to leaves through the stem.
