What do animal cells look like


Molecular Expressions Cell Biology: Animal Cell Structure

They should explain the structure of their cell and how it is adapted to its function. Encourage them to point out any aspects of the real cell which they could not show accurately on their model. They should all get the chance to work in pairs, giving their presentation to their partner. If you have time, you could choose the best models and ask those students to make a presentation to the whole class.

Information about cell structures for students to use as annotations on diagrams of plant and animal cells:. A structure may have more than one annotation. Some annotations apply to both plant and animal cells. Teacher resource for planning or adapting to use with pupils. Read each statement and then in your group decide, for each statement, whether it is true T or false F. Write the letter or symbol to show your decision in the middle column. Use the last column to explain your reasons.

Everything would certainly not be still. Cytoplasm is continually moving around. Molecules would be moving in and out of cells. In a muscle cell you might find yourself squeezed and released from time to time. The swishing of the streaming cytoplasm is likely to set up vibrations. Sound is vibration. If you could manage to shrink to fit in a cell your ears could probably manage to detect these vibrations as sounds! One of the plant cells in the photograph really measures about 0. Draw it in your book so its shape and proportions are nearly the same as in the picture.

If you were magnified by the same amount as your drawing of an animal cell, how far could you go in one stride? Children find this aspect of cells difficult to imagine and one of the main reasons for making a model is to show the 3D nature of the cell. Teacher resource to support teaching approaches.

Using models or analogies is a very powerful way of helping children to understand scientific ideas.

Used properly, models can also help to develop critical thinking. You can do this by helping children to evaluate the strengths and weaknesses of a model. A useful approach when you are planning a sequence of lessons based on a model such as the particle model might be:.

  4. Once students have a good understanding of the particle model, this will help them to understand concepts such as why materials have different properties, osmosis, Brownian motion, density, elements, compounds and chemical change. Introduction Your students will have been taught about cells in primary school. Focus on language to support understanding Researchers have established a clear link between language and learning. Activity 1: Working in pairs to discuss cells Before the lesson, draw diagrams of generalised animal and plant cells on the board, without labels. How big are cells? Case study 2: Looking at onion cells Mr Baguma had one microscope to use with his class.

    Activity 2:Thinking about the size of cells Remind students that you can only see cells with a microscope. Building Models of cells One way of helping your students to visualise things like cells or viruses or molecules is to let them build models. Case study 3: Making and assessing models Mrs Muthui had been teaching for 2 years.

    Activity 3: Making and presenting models In teaching about cells, you will have introduced your students to cells that are adapted to a particular function, and you will have encouraged them to draw diagrams of the cells in their notebooks.

Cellulose cell wall Information about cell structures for students to use as annotations on diagrams of plant and animal cells: A structure may have more than one annotation.

    The outer layer of this cell is firm and rigid. It is made of cellulose. It gives the cell a definite shape.

    The outer layer of this cell is not very rigid. It causes the shape of the cell to be flexible. This is a large central area in the middle of the cell. It is filled with liquid. This helps to make the cell firm and gives support to the whole plant.

    This structure controls what goes into and what comes out of the cell. This structure controls what the cell is like and how it works. This is a jelly like fluid containing many granules. Activities such as releasing energy and making proteins happen here. These structures are used to make food by photosynthesis. These are small vacuoles found in cells.

    They may contain food particles, chemicals made by the cell or germs that are being destroyed by the cell. Photographs of plant and animal cells as seen using a light microscope: Cells from a moss leaf. Cells from inside the human cheek. Statement True, false or unsure Comment — reasons for your choice 1 All cells have a nucleus. There is no colour in a cell. True, with some qualifications. See notes. All plant and animal cells have a nucleus.

    In some cells, the nucleus may have disintegrated by the time the cell reaches maturity. Red blood cells have a nucleus when they are developing. However, when they are mature and doing their job of carrying oxygen round the body, the nucleus has broken down. The whole cell is full of the oxygen-carrying pigment called haemoglobin. Bacterial cells are usually described as having a nuclear area, rather than a true nucleus, because there is not a nuclear membrane round the nuclear area. There is a cell membrane around all cells.

    True All cells have a cell wall. False Plant cells are surrounded by a cell membrane and outside this is a fairly rigid cell wall. The cell wall gives the plant cell a more definite shape than an animal cell. Animal cells do not have a cell wall.

    What are the Differences Between Plant Cells and Animal Cells?

    They are surrounded by a cell membrane only. A cell membrane is much more flexible that a cell wall. Chromosomes are found in the cytoplasm. False Chromosomes are found in the nucleus. The cell membrane controls what the cell will look like and how it behaves. False The nucleus controls what the cell looks like and how it behaves.

    The nucleus controls what passes into and out of a cell. False The cell membrane controls what passes into and out of a cell. A nucleus is smaller than a chloroplast.
