Do bacteria have chloroplasts?
Also, chloroplasts and mitochondria are found only in eukaryotic cells; bacteria and archaea do not have them.
What has no cell wall and no chloroplasts?
Monera (includes Eubacteria and Archeobacteria)
Individuals are single-celled, may or may not move, have a cell wall, have no chloroplasts or other organelles, and have no nucleus. Monera are usually very tiny, although one type, namely the blue-green bacteria, look like algae.
Why do plants need both chloroplasts and mitochondria quizlet?
Cells need both chloroplasts and mitochondria to undergo both photosynthesis AND cell respiration. After photosynthesis, which chloroplasts are needed for, which yields oxygen and glucose, plants need to break down the glucose and they use cell respiration to do this, which happens in the mitochondria.
Why do the cells of plant roots generally lack chloroplasts?
Why do the cells of plant roots generally lack chloroplasts? Because the roots are underground, so they cannot get light which is what chloroplasts need to carry out photosynthesis. … Plants and Bacteria Heterotrophs are animals and other organisms that must get energy from food.
Why do almost all eukaryotes have mitochondria but only some have chloroplasts?
1. All eukaryotic cells have mitochondria, but not all eukaryotic cells have chloroplasts. 2. Eukaryotic cells arose through endosymbiotic events that gave rise to the energy-producing organelles within the eukaryotic cells such as mitochondria and chloroplasts.
Why chloroplast are found in plant cell?
Chloroplast is specific to plant cell because plants are the autotrophs which can prepare their food by conversion of light energy to chemical energy. It is the vital photosynthetic pigment in leaves as it involves the conversion of light energy into chemical energy.
Why do plant cells have chloroplasts and animal cells do not?
In order to do photosynthesis, a plant needs sunlight, carbon dioxide (CO2) and water. Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make Page 2 energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
Why are there several chloroplasts in the plant cell?
There are several chloroplasts in a plant cell to maximize photosynthesis.
Why do you think that photosynthesis does not take place in the cells of the epidermis?
Answer: The epidermis has tiny pores called stomata (singular, stoma) that control transpiration and gas exchange with the air. For photosynthesis, stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen.
