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

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

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

  3. 3.This is a neuron. Tap the part that picks up signals coming from other neurons.

    Write the number of the part.

    1234

  4. 4.What does a ligament join?

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

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

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

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

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

  8. 8.Sort each type of muscle by whether we control it.

    Groups: Moves when we choose · Moves without our choosing

    • Cardiac muscle
    • Skeletal muscle
    • Smooth muscle
