The Basic Units of Life CLIL – Přírodopis pro 6.ročník ZŠ Ivan Rychlý What’s this? It’s a bat. The bat is an animal. What are these? They are animals. This is a plant. These are plants. What’s this? It’s a virus. These are viruses. This is a bacterium. These are bacteria. This is a fungus. These are fungi. There are five kingdoms of organisms. Viruses Plants Bacteria Animals Fungi What’s this? It’s a cell. You need a microscope to see some cells. How many cells are there in the picture? There are 33 cells. Which is which? an animal cell a plant cell a bacterial cell Plant cells can use photosynthesis, because ... ... they’ve got chloroplasts. What can you see in the cell? cell membrane cell wall vacuole nucleus nuclear membrane mitochondrion chloroplast cytoplasm This is a plant cell structure with organelles. cell membrane cell wall vacuole nucleus nuclear membrane mitochondrion chloroplast cytoplasm Which organisms have got cell walls around their cells? Plants Fungi Bacteria Animal cells haven’t got cell walls. Viruses aren’t cellular organisms. These are unicellular organisms. These are multicellular organisms. Read the text and check your worksheet. A) Cells are the basic units of life. Every cell has got a cell membrane, organelles and cytoplasm. B) Plants, animals and fungi have got a nucleus inside their cells. Around the nucleus there is a nuclear membrane. Read the text and check your worksheet. C) Bacteria are unicellular organisms. Bacterial cells are very small. They haven’t got a nuclear membrane, but they have got a cell wall. Read the text and check your worksheet. D) Viruses are smaller than bacteria. They aren’t cellular organisms. E) Fungi can be unicellular or multicellular organisms. Fungal cells have got a cell wall, but they haven’t got chloroplasts. Fungi can’t use photosynthesis to get food. Read the text and check your worksheet. F) Plant cells have got a cell wall, chloroplasts or vacuoles. These cells can use photosynthesis to get food. G) Animal cells haven’t got a cell wall and they haven’t got chloroplasts. There are five kingdoms of organisms. Viruses Plants Bacteria Animals Fungi Thank you. Bye!
