Characteristics that are always present in living organisms are Metabolism, Cells and Reproduction.
Answer:
light-dependant reactions and Calvin cycle:)
Explanation:
Well, In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
Answer: Leaves are adapted for photosynthesis and gaseous exchange.
Explanation: They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapor can then escape from inside the leaf.
The genetic base of the shape of orchid is very complex.
Mendelian traits are described as simple traits determined by one gene. The different alleles of the gene contribute to the difference in the trait. This is true for some traits in plants, animals including humans and other organisms, but not for the shape of orchids.
The shape of orchid flowers is determined by the ABCDE group of genes that are responsible for the body plan in plants. These genes are the equivalent of HOX genes of animals.
The protein products of different genes of the ABCDE group interact with each other in complex ways creating different shapes of orchids.
Answer:
- to have cell walls made of chitin
- eukaryotic heterotrophs
Explanation:
Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.
The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.
Kingdoms include different phyla closely related.
The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.
All the members of the kingdom
-
Lack mobility, growing on the ground, organic matter, or other surfaces.
- They all have a rigid cell wall composed of chitin.
- They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.
- Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.
- Reproduction is by spores, which are resistant to adverse environmental conditions.
