Quá trình tổng hợp các chất mới.
Tập hợp các phản ứng hóa học xảy ra trong cơ thể sinh vật.
Chỉ gồm quá trình dị hóa.
Quá trình đồng hóa có đặc điểm:
Giải phóng năng lượng.
Phá vỡ các chất phức tạp thành đơn giản.
Tiêu tốn năng lượng để tổng hợp chất mới.
Diễn ra chủ yếu trong ti thể.
Năng lượng chủ yếu trong tế bào được dự trữ dưới dạng:
ATP
ADP
Glucose
Oxi
Quá trình hô hấp tế bào diễn ra chủ yếu ở:
Nhân

Khi đất bị ngập úng lâu ngày, cây thường héo vì:
Rễ bị thối
Thiếu oxi cho hô hấp rễ
Thiếu nước trong đất
Mất cân bằng ion

The process of digestion always consumes energy.
True
False
ATP is considered the 'energy currency' of the cell.
True
False
Water is absorbed by roots mainly due to root pressure.
True
False
Plants absorb minerals in dissolved form.
True
False
If the soil is too salty, plants will absorb water faster.
True
False
Define metabolism.
The sum of all chemical reactions occurring in an organism to sustain life.
The process of breaking down only carbohydrates in the body.
The movement of muscles to produce energy.
The absorption of nutrients in the small intestine.
Distinguish between anabolism and catabolism.
Anabolism: synthesis, energy-consuming. Catabolism: breakdown, energy-releasing.
Anabolism: breakdown, energy-releasing. Catabolism: synthesis, energy-consuming.
Anabolism: both synthesis and breakdown, energy-neutral. Catabolism: neither synthesis nor breakdown, energy-neutral.
Anabolism: breakdown, energy-consuming. Catabolism: synthesis, energy-releasing.
What is the main energy source for cells?
ATP
DNA
Glucose
Oxygen
What is the role of mitochondria in plant cells?
Site of cellular respiration, produces ATP.
Site of photosynthesis, produces glucose.
Stores genetic information, controls cell activities.
Synthesizes proteins, assembles amino acids.
Name two pathways for water absorption in roots.
Apoplast and symplast pathways.
Transpiration and guttation pathways.
Phloem and xylem pathways.
Diffusion and osmosis pathways.
How does water leave the leaf?
Mainly through stomata.
Through the roots.
By absorption from the air.
By photosynthesis.
What is the function of transpiration?
Helps in water, mineral transport and cooling of leaves.
Increases the rate of photosynthesis in roots.
Produces food in the stem.
Absorbs oxygen from the air.
Name two types of mineral transport in roots.
Passive diffusion and active transport.
Osmosis and transpiration.
Photosynthesis and respiration.
Evaporation and condensation.
Why do plants need minerals?
For growth and metabolic functions.
To produce oxygen only.
To attract insects.
To prevent water loss.
Why do plants die easily when they are waterlogged?
Due to lack of oxygen, roots cannot respire and cannot absorb water.
Because waterlogged soil provides too many nutrients to the plant.
Because waterlogged soil increases the rate of photosynthesis excessively.
Because waterlogged soil causes the plant to grow too quickly.
The relationship between the processes of assimilation and dissimilation in cells is:
Assimilation builds up cellular components, while dissimilation breaks them down.
Both assimilation and dissimilation break down cellular components.
Assimilation and dissimilation are unrelated processes in cells.
Dissimilation builds up cellular components, while assimilation breaks them down.
Plants wilt when the soil is too salty because:
water moves out of the plant roots due to osmosis
the plant absorbs more water from the soil
salt provides extra nutrients for the plant
the plant produces more chlorophyll
A potted plant grown indoors has yellowing leaves and stunted growth. What is the most likely cause and solution?
Lack of sunlight and nutrient deficiency; move the plant to a brighter spot and fertilize it.
Overwatering; water the plant more frequently.
Excessive sunlight; place the plant in a darker area.
Pest infestation; spray the plant with insecticide.
