Cell Structure and Function National 5 Cell Biology Cell Structure and Function

We are learning to: Identify different cell types Identify the parts of cells State the function of the parts of the cells Describe similarities and differences between different cell types 21/11/2018

What I'm looking for: Table showing the different functions of each part of the cells Labelled diagrams of each cell type A sentence to describe the similarities and differences between the different cell types

Animal and Plant Cells Plant and Animal cells

Activity One Watch the video “What is a cell?” closely You will use this information to complete a table

Activity One Start Timer 7 Using information from the video and in your booklet- complete table in your booklet 3.5

Organelle Cells present in Function Cell wall Plant, fungal and bacterial Provide shape and support to the cell Mitochondria Animal, plant and fungal Site of aerobic respiration Chloroplasts Some plant cells Site of photosynthesis Cell membrane All cells Controls the movement of substances in and out of cells Cytoplasm Site of chemical reactions Vacuole Plant and fungal Fluid filled sac containing water, sugars and salts Nucleus Controls cell activities and contains genetic information Ribosome Site of protein synthesis Plasmids Bacterial Small circular DNA

Activity Two Using the information provided, match the organelle function and picture with its name Check with your teacher Label diagrams in your summary booklet

Bacterial Cell

Activity Three Describe the similarities and differences between Plant and animal cells Plant and fungal cells (Hint! Mention the cell wall) Fungal and bacterial cells (Hint! Think of organelles)

Plant and Animal Cells Similarities Differences Nucleus Cell membrane Cytoplasm Ribosome Mitochondria Plant cells also have a cell wall chloroplast vacuole

Plant and Fungal Cells Similarities Differences Nucleus Cell membrane Cytoplasm Ribosome Mitochondria The cell wall of a plant cell is made of cellulose Fungal cells do not have chloroplasts- cannot make their own food

Fungal and Bacterial Cells Similarities Differences Ribosome Cell membrane Cytoplasm Cell walls are structurally different Fungal cells have mitochondria, nucleus and a vacuole Bacterial cells do not have a nucleus, contain extra DNA plasmids

I can: Identify different cell types Identify the parts of cells State the function of the parts of the cells Describe similarities and differences between different cell types
