Year 10 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.Sort each type of muscle by whether we control it.

    Groups: Moves when we choose · Moves without our choosing

    • Cardiac muscle
    • Smooth muscle
    • Skeletal muscle

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

  3. 3.Which simple permanent tissue has thick walls stiffened with lignin and is made mostly of dead cells?

    • a) Collenchyma
    • b) Sclerenchyma
    • c) Epidermis
    • d) Parenchyma

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

  5. 5.Two onion bulbs grow roots in water. On day 3 one bulb's root tips are cut off by about a centimetre. What happens over the days that follow?

    • a) The cut roots lengthen faster, having been pruned
    • b) Both sets of roots keep lengthening at the same rate
    • c) The uncut roots keep lengthening and the cut ones stop
    • d) Both sets of roots stop lengthening

  6. 6.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) Bone has living cells and cartilage has none
    • d) Cartilage is a kind of muscle rather than a connective tissue

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

  8. 8.What does a ligament join?

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