1) They are both Eukaryotic cells.
2) They lack cell wall.
Eukaryotic cell are cells that have a nucleus enclosed within membranes. Also, there are numerous membrane bound organelles which includes Golgi apparatus, mitochondria, Endoplasmic reticulum and Chloroplast.
Cell wall is rigid in nature and semi-permeable protective layer found in cells. They are positioned next to the cell membrane in most fungi, bacterial and plant cells but absent in Animal cells. Furthermore, they perform many important functions in the cell which includes protection, structure and support.
However, both human being and Ameoba have Eukaryotic cells and lack cell wall.
Answer;
-Green plants are responsible for oxygen in the atmosphere.
Explanation;
-Green plants undertake a process of photosynthesis, in which they use energy from the sun, carbon dioxide and water to form simple sugars and also release oxygen to the atmosphere. The simple sugars from the process may be used by the cells for energy or be stored in form of energy for future use.
-Oxygen is a product of photosynthesis which is released to the atmosphere.
Answer:
Mass of a pure substance is directly proportional to it's density.
Explanation:
When the size of a pure substance increases, it's density increases too. And when the size of the substance decreases, the density decreases too.
Osmosis provides the primary means by which water is transported into and out of cells. The turgor pressure of a cell is largely maintained by osmosis across the cell membrane between the cell interior and its relatively hypotonic environment.
