Questions and Answers

Match the following plant processes with their descriptions:

Photosynthesis = Process of manufacturing carbohydrates from raw materials using light energy Nutrition = Taking in useful substances for growth and development Chlorophyll = Green pigment inside a chloroplast molecule Glucose production = Conversion of light energy into chemical energy

Match the following components of photosynthesis with their roles:

Chloroplast = Location where photosynthesis takes place Enzymes = Aids in carbon combining with water during photosynthesis Light energy = Source of energy for the process of photosynthesis Carbon and water = Raw materials used to produce glucose in photosynthesis

Match the following parts of a chlorophyll molecule with their functions:

Chlorophyll molecule = Absorbs energy from sunlight Released energy = Used to make carbon combine with water Glucose = Contains energy from light Sunlight = Provides energy for the chlorophyll molecule

Match the following leaf parts with their functions:

Epidermis (upper) = Secretes a waxy substance called the Cuticle that covers the upper epidermis Epidermis (lower) = Has small openings called stomata Palisade Mesophyll Cells = Contains many Chloroplasts to carry out photosynthesis Spongy Mesophyll Cells = Have air spaces that facilitate the diffusion of Carbon dioxide through the cell wall and cell membrane of each cell Signup and view all the answers

Match the following leaf adaptations with their functions:

Stem and Petiole = Exposes most of the leaf's surface to Sunlight and Air Large surface area = To expose the cells to the largest amount of Sunlight as possible Thin layered = Allows sunlight to reach all cells and Carbon Dioxide to diffuse in and Oxygen to diffuse out Palisade cells are arranged end on (vertically) = Keeps as few cell walls as possible between Sunlight and Chloroplasts Signup and view all the answers

Match the following chlorophyll-related features with their functions:

Chloroplasts arranged broadside on (horizontally) = Exposes optimum amount of chlorophyll to Sunlight Chlorophyll present in cells in the Mesophyll layer = Absorbs energy from Sunlight so that Carbon Dioxide combines with Water No Chloroplasts in Epidermal layer = Allows Sunlight to reach cells in the mesophyll layer Chlorophyll arranged on flat membranes inside chloroplasts = Exposes maximum amount of chlorophyll to sunlight Signup and view all the answers

Match the following transport vessels with their functions:

Xylem tube = Carries water to the Mesophyll Cells Phloem tube = Takes away substances that the leaf has made such as Sucrose Signup and view all the answers

Match the following uses of Glucose in the Plant’s Nutrition with their notes:

Used for Energy = Energy can be released from glucose using Aerobic respiration Used to make Proteins = Nitrate molecules are mixed with glucose to form strands of amino acids which are bound into Proteins Used to make organic substances = Signup and view all the answers

Study Notes

Plant Processes

Respiration: process of releasing energy from glucose
Photosynthesis: process of converting light energy into chemical energy

Components of Photosynthesis

Light-dependent reactions: produce ATP and NADPH
Light-independent reactions (Calvin cycle): produce glucose
Chlorophyll: absorbs light energy
Stomata: regulate CO2 and O2 exchange
Thylakoids: contain pigments, including chlorophyll

Chlorophyll Molecule

Head: contains magnesium ion, absorbs light energy
Tail: embedded in thylakoid membrane, anchors chlorophyll

Leaf Parts

Mesophyll: inner tissue where photosynthesis occurs
Cuticle: waxy outer layer, prevents water loss
Epidermis: outer layer, protects leaf from environment
Veins: xylem and phloem vessels, transport water and nutrients

Leaf Adaptations

Thick cuticle: reduces water loss in arid environments
Stomata: regulate CO2 and O2 exchange, conserve water
Waxy coatings: prevent water loss, reflect light

Chloroplasts: contain chlorophyll, site of photosynthesis
Fluorescence: energy released as light, indicates photosynthesis

Transport Vessels

Xylem: transports water and minerals from roots to leaves
Phloem: transports sugars, amino acids, and hormones throughout plant

Uses of Glucose in Plant Nutrition

Energy source: provides energy for plant growth and development
Building block: used to synthesize other organic molecules
Stored energy: stored in roots, stems, and leaves for later use
