Çalışma kâğıtları

Pratik çalışma kâğıdı

Cevabı açmadan önce her soruyu dene — öğrenme tam da o zorlanmada olur.

1. Name three structures found in plant cells but not in animal cells.
Think about photosynthesis and support.

Cell wall, chloroplasts and the permanent vacuole.

2. Which organelle is the site of aerobic respiration, and which carries out photosynthesis?
One releases energy from glucose; the other captures light.

Mitochondria — aerobic respiration. Chloroplasts — photosynthesis.

3. Explain why a root hair cell does not need chloroplasts.
What is the job of a root hair cell, and where does it live?

Root hair cells absorb water underground in the dark — there is no light for photosynthesis, so chloroplasts would be useless. They are specialised for absorption instead.

4. Put these in order of size, smallest first: cell, organ, tissue, organelle, organ system.
Start from the microscopic.

Organelle → cell → tissue → organ → organ system.

  • Cells are the basic building blocks of all living organisms.
  • Nucleus holds genetic material and controls the cell; mitochondria release energy in respiration.
  • Plant cells also have a cell wall, chloroplasts (photosynthesis) and a permanent vacuole.
  • Cells differentiate to become specialised — structure matches function.
  • Organisation goes: organelles → cells → tissues → organs → organ systems.
