Magnification
Magnification
I can identify cells using a magnifying glass and a microscope. (Knowledge)
I can defend the fact that plant and animals are comprised of cells too small to be seen without magnification. (Reasoning)
I can explain that plants and animals are comprised of cells too small to be seen without magnification. (Reasoning)
I can gather evidence using technology, such as magnifying glasses and microscopes, to support the claim that plants and animals are made up of cells too small to be seen without magnification. (Skill)
Cells are too small to be seen with the naked eye and the microscope makes them visible. Smaller cells appear under the microscope that are not visible with the naked eye. A microscope increase magnification, which allows the user to see the organelles of a cell, and what organelles can be seen to differentiate between plant and animal cells. A magnifying glass can help us see parts of a plant, but the microscope provides enough magnification to see the presence of cells. The differences in plant and animal cells cannot be seen without the use of the microscope.

All cells contain specialized, subcellular structures that are adapted to keep the cell alive. There are two types of cells on Earth; prokaryotes, and eukaryotes. Some of these structures release energy, while others produce proteins, transport substances, and control cellular activities. Collectively, these structures are called organelles. Plant and animal cells both contain organelles, many of which are found in both types of cells. However, there are some organelles (such as chloroplasts, the cell wall, and large vacuoles) that are only found in plant cells.
The nucleus is one of the larger organelles, has a round shape and unique structure, contains all the DNA of a cell, and controls the activities or functions of the cell - called the control center. It is one of the larger organelles inside the cell.
The cytoplasm is a jelly-like substance found inside all cells, that holds the organelles of the cell in place.
Chloroplasts use energy from the sunlight to produce food for plant cells (photosynthesis).
Mitochondria release energy for the cell.
The Golgi apparatus packages and distributes substances.
The vacuole maintains turgor pressure in plant cells.
Cell membrane (plasma membrane) separates the interior of the cell from the outside environment and controls what goes in and out of the cell, surrounds the cell and is located inside the cell wall.
Cell wall is the firm outer nonliving layer that surrounds the cell membrane, providing a barrier, and encloses and supports the cells of most plants, bacteria, and fungi; provides structure, shape and stability to the cell, to hold the plant upright in place of a skeleton.

Structure of Plant and Animal Cells
Structure of Plant and Animal Cells
I can identify structures that differentiate animal and plant cells. (Knowledge)
I can compare the structures of an animal and plant cell. (Reasoning)
I can construct an explanation to explain the differences between the structures of plant and animal cells. (Reasoning)
Cells are the fundamental units of life from which all other living things are made. They contain all the molecules and structures needed for individual cell survival and the survival of the organism as a whole. Different cells have different subcellular structures, but all eukaryotes contain the same three parts: the nucleus, the cell membrane, and the cytoplasm. Plant and animal cells are both eukaryotic cells, meaning they possess a defined nucleus and membrane-bound organelles. They share many common features; however, their structure is different. The animal cell has a flexible round shape which indicates an absence of the cell wall, while the plant cell has a consistent rigid rectangular shape which indicates the presence of a cell wall.
Plant cells have a rigid rectangular shape because of the cell wall. Plant cells contain a structure that allows them to create their own food through photosynthesis while animal cells cannot.
Animal cells can bend more than a plant cell because they do not have a cell wall. The lack of a cell wall in an animal cell makes it less rigid and easier to bend.
