Why is the cell wall absent in animal cell?
1) Define cell wall; 2) Animal cells are covered by a sugar-protein coat; 3) Animal cells are surrounded and protected by other Animal cells;
How many cells are in the human body at birth?
As HUMANS, stem cells as they develop into our own specialised cells, as all animals start off as a fertilised egg, and it is our genetics that transform our stem cells into the many different specialised cells we need as humans.
What are 3 types of body cells from animal cells?
hhhheeeeelllloooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
What are 3 elements that plant cells have and animal cells do not?
nothing
What do plant and animal cells differ by?
1. Cell wall present in plant cells and absent in animal cells. 2. Centrioles present in animal cells and absent in plant cells. 3. Chloroplasts & other plastids are present in plant cells; these are absent in animal cells. 4. Plant cell usually has a large vacuole, animal cells have small vacules. 5. Lysosomes are present in animal cells, hardly seen in plant cell. 6. The cell shape is defined in plants due to presence of cell wall, it is irregular in animal cells.
What 3 organelles that are found in plant cells that are not found in animal cells.?
The cell wall, chloroplasts and a permanent vacuole are not found in animal cells.
What are 3 differences between plant and animal cells?
animal cells have centrioles which plants do not have. animal cell are heterotrophs and plants are autotrophs plants cells have cell walls composed of cellulose and animal cells do not have any.
Name two specialised animal cell and one specialised plant cell?
1. Parenchyma Cells. These cells are the most general of plant cells. They consist of thin flexible cell walls. They contain a large central vacuole and can carry out most of the metabolic functions of the plant. Mesophyll cells of the leaf are parenchyma cells. The fleshy tissue of most fruits also contain much parenchyma.2. Collenchyma Cells. These cells have a much thicker primary wall than the parenchyma cell. Grouped in strands or cylinders they support young plants. -3. Palisade Cells. These cells contain lots of chloroplasts, which absorb light energy for photosynthesis.
What are some differcen between animal and plant cells?
1) Animal cells dont have cell wall but plants do 2) Animal cells dont have chloroplast and plants do 3) Animal cells are smaller than plant cells
What are 3 types of cells?
plant animal and human
Name 3 specialised animal cells?
red blood cell is one, nerve cell is two and white blood cell is three
What 3 structures are not found in animal cells that are in plant cells?
The starch grains, chloroplast and cell wall (vacuoles are larger in plants cells, but small scattered ones can be found in animal cells)
