What do plant cells have that animal cells do not?

B2 REVISION – CHAPTER 1 – CELLS

Sketch and label a plant and an animal cell; Use pictures and words to describe how substances can move in and out of cells by diffusion What is the function of: Nucleus – Mitochondria Ribosome Chloroplasts Cell Wall Label the yeast and bacteria and write 4 bullet points about the characteristics of each one Draw and label 2 specialised cells. Explain their structure is adapted to suit their function

KEY WORDS:

Describe the difference between aerobic and anaerobic respiration in yeast

B2 REVISION – CHAPTER 1 – Cell, Tissues & Organs

Bacteria & Yeast

Structure

Animal & Plant Cells

Purpose

Controls the cells activities

Plant/Animal/Both

Cytoplasm Where is the genetic material in a bacteria cell?

How many cells make up yeast?

Both Specialised Cells Cells are specialised to carry out a specific function. The structure gives a clue to its function.

Diffusion Is how dissolved substances and gasses move into and out of cells.

Mitochondria Ribosomes Protein synthesis takes place Contain chlorophyll, absorb light energy to make food Plant Vacuole If a cell has many ribosomes it is making a lot of protein, which type of cell might it be?

KEY WORDS: Gland cells Nucleus Algal cell Cellulose Chloroplast ASSESSMENT:

B2 REVISION – CHAPTER 1 – Tissues, organs and organ systems

A tissue is ____________________ ____________________________ Tissue Function Animal/Plant What is an organ?

What are the main organs of a plant?

Label the image below and explain the function of each tissue Glandular Epithelial What is an organ system?

Epidermal Mesophyll The digestive system’s function is Label the diagram> For each organ describe the function it performs Xylem phloem Adaptations for exchange – For each one of the organs below write down the substance that is exchanged • Lungs: • Small intestine: • Kidneys • Make a list of the adaptations you may see on these organs: 1. 2. 3. cells ------- ----------- ---------------- ---------------------
