Year 9 Science — Plant and animal tissues

Name the three meristems and the permanent tissues they become, match each plant and animal tissue to its job, and tell the joints and muscle types apart by what they do.

Name: ________________________

Before you start

Three simple permanent tissues, side by side and each one named.

123
  1. 1. Thin walls the whole way round — parenchyma
  2. 2. Corners thickened with pectin — collenchyma
  3. 3. Thick lignified walls — sclerenchyma

Parenchyma is alive and stores food. Collenchyma is alive and bends. Sclerenchyma is mostly dead cells, and it is what makes a coconut husk hard.

  1. 1.Match each plant tissue to the job it does.

    • Xylem
    • Phloem
    • Epidermis
    • Sclerenchyma
    • Collenchyma
    • Forms the outer protective layer
    • Supports a part while letting it bend
    • Carries water and minerals up from the roots
    • Carries food from the leaves to the rest of the plant
    • Makes a part hard and strong with lignified walls

  2. 2.How many pairs of ribs make up the human rib cage? Answer with a number.

  3. 3.Which iron-rich protein in the red blood cells gives blood its colour? Give the one word.

  4. 4.Bone and cartilage are both connective tissues. What makes one hard and the other springy?

    • a) Bone has a rigid matrix with calcium and phosphorus compounds; cartilage's matrix is soft and jelly-like
    • b) Bone has living cells and cartilage has none
    • c) Cartilage is a kind of muscle rather than a connective tissue
    • d) Cartilage has a rigid matrix and bone has a jelly-like one

  5. 5.Which muscle type has branched cylindrical fibres with a single nucleus and faint striations?

    • a) Skeletal muscle
    • b) Cardiac muscle
    • c) Smooth muscle
    • d) Epithelial muscle

  6. 6.Put a message's journey through a neuron in order, starting from The dendrites pick the message up from another neuron.

    • The cell body, which holds the nucleus, takes it in
    • The axon carries it away as a long fibre
    • The axon terminals pass it on to the next cell
    • The dendrites pick the message up from another neuron

  7. 7.What does a ligament join?

    • a) A nerve to a muscle
    • b) A muscle to a bone
    • c) One bone to another bone
    • d) A muscle to another muscle

  8. 8.What are the pores in a leaf's epidermis called? Give the one word.

Answer key — Year 9 Science — Plant and animal tissues

  1. 1. Xylem → Carries water and minerals up from the roots; Phloem → Carries food from the leaves to the rest of the plant; Epidermis → Forms the outer protective layer; Sclerenchyma → Makes a part hard and strong with lignified walls; Collenchyma → Supports a part while letting it bend
  2. 2. 12
  3. 3. haemoglobin
  4. 4. a) Bone has a rigid matrix with calcium and phosphorus compounds; cartilage's matrix is soft and jelly-like
  5. 5. b) Cardiac muscle
  6. 6. 1. The dendrites pick the message up from another neuron 2. The cell body, which holds the nucleus, takes it in 3. The axon carries it away as a long fibre 4. The axon terminals pass it on to the next cell
