A cell needs chloroplasts
Mitochondria needs sugar.
Sugars are the fuel for respiration. Respiration fulfills the energy need of cell
a kind of sugar your body needs for energy
Mitochondria. However, it only converts glucose (a simple sugar) to ATP (usable energy). There are many more enzymes that break down complex sugars to simple sugars. Glucose is the ONLY form of sugar that the mitochondria can convert to ATP. Other simple sugars like galactose and fructose need to be converted to glucose first.
Cells need glucose as a source of energy to carry out their various functions. Glucose is broken down through cellular respiration to produce ATP, which is the energy currency of the cell. Without glucose, cells would not be able to generate the energy needed to survive and perform essential activities.
I would say that it needs to converted into ATP because the sugar molecules turn into chemical energy that can be used by a cell to carry out life processes. Cells can breakdown ATP quickly to release the energy.
You generally need a catalyst or a mechanism to convert the energy. For example to convert fuel (a mass) into thermal energy, oxidizer and a spark are needed.
The cell gets its energy when nutritional components of food are oxidized by the oygen of inspiration in mitochondria. When the cells need energy a phosphate bond breaks and energy is released for performing particular cellular activity.
They get it from sugar which they get from the sun!
Plants need energy for photosynthesis, which is the process they use to convert sunlight into chemical energy in the form of glucose. This energy is essential for the plants to grow, develop, and produce food for themselves.
Its because the plant needs to be stable because it would be really floppy, and the animal cell does not because it can move around the animal and it does not need to be stablised. Animal cells do not have chlorophyll because they don't need it. Plant cells need them because they take in sunlight and turn it into a sugar that is used for food for energy. Animal cells do not get their energy from the sun directly, they get it from oxygen. Animal cells do not photosythesise, which is what chlorophyll is for.
because a human body looses energy during the whole day . sugar=energy :)
