Life Processes
This chapter page turns the high-level subject view into an ordered learning slice, with direct links from curriculum items into topic and skill detail.
Ordered curriculum items
Each curriculum item can now route into topic and skill-level detail.
2
Why life processes matter
Connect cellular needs with energy, materials and waste removal.
3
How plants make food
Explain photosynthesis using raw materials, products and conditions.
4
Write photosynthesis equation
Represent photosynthesis using words and symbols appropriately.
5
Photosynthesis requirements
Connect leaf structures and conditions with food production.
6
Track digestion in humans
Follow ingestion, digestion, absorption, assimilation and egestion through organs.
7
Digestive enzymes in action
Match enzymes and secretions with the nutrients they help digest.
8
Compare nutrition modes
Distinguish autotrophic, saprotrophic and holozoic nutrition.
9
Breathing or respiration?
Separate gas exchange from energy release in cells.
10
Aerobic vs anaerobic
Identify oxygen use, products and energy release differences.
11
Plant respiration
Describe gas exchange through stomata, lenticels and roots.
12
Path of air
Identify organs involved from nostrils to alveoli.
13
Gas exchange in lungs
Relate thin walls, large surface area and blood supply to diffusion.
14
Water transport in plants
Describe root absorption, xylem transport and transpiration pull.
15
Food transport in plants
Describe translocation through phloem using energy.
16
Blood components
Match plasma, red cells, white cells and platelets with their roles.
17
Double circulation path
Follow oxygenated and deoxygenated blood through heart, lungs and body.
18
Heart structure and job
Relate chambers, valves and vessels to blood flow direction.
19
Compare blood vessels
Use structure and function to distinguish the three vessel types.
20
Why excretion is needed
Connect metabolic wastes with toxicity and internal balance.
21
How urine forms
Explain filtration, reabsorption and urine formation in simple terms.
22
Path of urine
Identify kidneys, ureters, urinary bladder and urethra.
23
Plant waste removal
Describe storage, diffusion, transpiration and shedding as waste removal methods.
