Answer:
Explanation:
Photosynthesis is the process plants use to convert energy from the sun into usable energy for their cells. Plants use the light energy of the sun, carbon dioxide, and water to make glucose (a sugar), and oxygen. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.
Answer:
All options are correct
Explanation:
Fossils are the remains of organisms (animals and plants) preserved in a rock. Scientists (geologists & palaebiologists) have used fossils to study the diversity of organisms in the past. This is based on their preserved morphological features. For example, several species of foraminifera has been identified in the rocks. Among them, some species are present today whereas others have become extinct.
Similarly, fossils are the indicators of past climate (e.g. temperature) as well. This means, if a specific species can survive at a particular temperature, its presence suggest that particular environment. For example, corals survive in tropical waters at specific depth and sunlight. So, if we find corals fossils, the cliamte of that particular age would be roughly the similar.
In the end, fossils can also provide evidence of orogeny (mountain building) process. These are typically plants fossils which cannot move and their remains are preserved in the folding rocks.
Answer:
The correct answer is option a. Membranes; chloroplast.
Explanation:
Photosynthesis is the process is specific to green plants and other photosynthetic organism converting light energy into storage energy by forming glucose from carbon dioxide and water and oxygen released as a byproduct.
This process involves the green pigment present in the plants called chlorophyll located in the chloroplast. The chloroplast is a double membrane organelle present in green plants. The membranes of the chloroplast are the site of photosynthesis.
Thus, the correct answer is option a. Membranes and chloroplast
The way that I know it is that cells make up tissue, tissue makes up organs, and organs make up organ systems.
The answers are "water and mineral ions" and "amino acids and sucrose" respectively.
For the xylem, it usually transports water and mineral ions that are absorbed from the root hair cells up to the leaves, where photosynthesis take place. Water is one of the necessary substance for photosynthesis to take place, while different mineral ions can help the plant by for example Magnesium ions can help produce chloroplast.
While phloem transports amino acid and sucrose from the location of production (eg. Leaves by photosynthesis) to the place where it is used or stored. Plant needs these substances to generate energy for activities such as growth by for example cellular respiration. This process is called translocation.
Both of these tubes help transport substances in the plant, in order to keep the plant alive.
