Answer:
Cellulose
Explanation:
Cell walls made of cellulose are only found around plant cells and a few other organisms. Cellulose is a specialized sugar that is classified as a structural carbohydrate and not used for energy. ... While cell walls protect the cells, they also allow plants to grow to great heights. You have a skeleton to hold you up.
Answer:
The amount of biomass in terrestrial ecosystem is small compared to that of the aquatic ecosystem
Explanation:
Terrestrial biomass generally decreases markedly at each higher trophic level. Terrestrial producers are grasses, trees or shrubs. They have a much higher biomass than the animals that consume them. The marine biomass increases at each higher trophic level.
The biomass of consumers is larger than the biomass of primary producers. The primary producers in the ocean are tiny phytoplankton that grow and reproduce rapidly, so a small mass can have a fast rate of primary producers. In terrestrial ecosystem, primary producers grow and reproduce slowly, so a much larger mass is needed to achieve the same rate of primary production.
Vacuole can occupy up to 90% of the cell volume and can exert turgor pressure against the cell membrane when it acquires water.
In biology, a vacuole is a membrane-bound space found in the cytoplasm of a plant cell.
These are large size compartments that can occupy up to 90% volume of water.
In fully grown plants, vacuoles play a very significant role as they help out in plant growth, storing water, disposing of waste materials, and protecting cells against external barriers.
In sum, vacuoles are generally small in size but important cell organelles that are present in bacteria, fungi, and protozoa.
