How were the plant slides and the animal slides alike? How were they different? Did your observations support your predictions that you made at the beginning of the Explore. Draw Conclusions
What are cells? Cells are the smallest units of living things that can carry out the basic processes of life. frog cells amoeba cell BrainPop- Cells
What are cells? What is an organism? An organism is a living thing made of the same tiny building blocks. From the smallest organism to the largest, they are all made of. cells A cell is the smallest unit of living things that can carry out the basic processes of life. What are life processes? moving parts of the body, reproduction, responding and reacting, getting food to stay alive, getting rid of waste, turning food into energy
Where do cells come from? Cells come from other cells. Every cell in every living thing on Earth originally came from another cell. A cell divided, or split into two cells, and so did the cell before that, and so on. Think about it this way where did you come from? Where did your parents come from?
What types of cells are there? Scientist have discovered 1,500,000 different kinds of organisms. Scientist believe there are still more than 1 billion unicellular organisms that have not been identified. A unicellular, or one-celled, organism is made of a single cell that carries out its life processes. If unicellular is one celled, what is an organism that is made up of more than one cell called? multicellular
Identify the parts of the cells *Animal Cell * Plant Cell Animal Cell Both plant and animal cells perform life processes by using organelles. Organelles have functions that help keep the cell alive.
What is inside an animal cell? nucleus vacuoles cytoplasm cell membrane mitochondria
What is inside a plant cell? mitochondria vacuole nucleus cytoplasm cell membrane chloroplast cell wall BrainPop- Cell Structures BrainPop- Specialization
Structures Animal Cell pg 30 Plant Cell pg 32 Cell Membrane Cytoplasm Nucleus Mitochondria Vacuole a flexible layer around the outside of the cell, like skin, controls what moves in and out of the cell gel like liquid, occupies the area from the nucleus to the cell membrane, supports cell structure, mostly water, constantly moving cell s control center, large round organelle, found in center, sends signals to all other parts Oval, membrane organelles that supply energy for the cell, tiny power plant Membrane-covered structure used for storage, some have many small, some have none same same same same Same, except only have one large central vacuole Cell Wall none An additional outer covering for strength Chloroplast none where plants make their food, green b/c chlorophyll
Compare and Contrast How can you tell the difference between a typical plant cell and a typical animal cell? Plant cell: has chloroplasts, cell wall Both: have cell membrane, organelles Animal cell: has many or no vacuoles Cells Alive
How are cells organized? Cells form tissues, tissues form organs, and organs work together in organ systems. cell tissue organ organ system All of the cells, tissues, organs, and organ systems form an organism.
Vocabulary Words for Lesson 1 cell unicellular organism multicellular What is a living thing made of tiny building blocks called? an organism A is the smallest unit of a living thing that can carry out the basic processes of life. cell What is an organism that is made up of more than one cell? multicellular A, or one-celled, organism is made of a single cell that carries out its life processes. unicellular
Review What are some examples of organisms? plants, bacteria, fungi, algae, protists, animals Where do cells come from? other cells Where are animal and plant cell s organelles found? in the cytoplasm Where is waste stored in a cell? vacuoles
Review Do you think that a cell would function without a nucleus? Most cells would not be able to function without the nucleus. The nucleus controls the cells activities. A cell would not be able break down food to provide energy, grow, or move without a nucleus. A red blood cell does not have a nucleus and still functions. Do plants need to eat food? No, they make their own food.
Review What helps plants get energy and make food? sunlight
