Euglena is a unicellular organism with both chloroplasts and mitochondria. If scientists remove all of the chloroplasts from a E
katrin2010 [14]

Answer:

Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is  a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.

If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.

Please help me!! Describe the effect of surface area and pores on cells.
ivanzaharov [21]

Explanation:

Surface area and pores play important roles in the cell.

Pores are the tiny holes on the surfaces of a body. They help to facilitate movement of materials in and out of the cell.

The surface area is the amount of space the surface of a cell occupies.

  • Pores in a cell needs to be in proper shape in order to facilitate movement of materials.
  • When the pores in a cell are too large, too much materials are bound to leave the cell. Tiny pores makes it difficult for the cells to have enough materials to function properly well.
  • The surface area of a cell allows for the diffusion of materials in and out of cell.
  • The larger the surface area of a cell, the more and better reactions takes place because they will receive important life sustaining resources.
