Plants and other producers make their food using photosynthesis True False

Biology

Answer:

True

Explanation:

Producers are unique set of organisms that begins a food chain or web. They are not dependent on any other organism for energy source (autotrophs). This is because of their ability to capture light energy from sunlight and use it to power the process of making their own food called PHOTOSYNTHESIS.

Photosynthesis is a unique feature of all autotrophic organisms like plants, planktons etc. It involves the use of an inorganic source (CO2) to synthesize organic food in the presence of sunlight. Plants and other producers obtain energy directly from the sun, hence, they are called PRODUCERS because they start a food chain in an ecosystem. Other organisms called CONSUMERS rely on them for energy.

How can two organisms with a dominant trait for a specific feature produce an organism with a recessive trait for the same featu

Liono4ka [1.6K]

Answer:

If the two organisms are heterozygous for the dominant trait.

Explanation:

For every trait, a diploid organism receives two forms of gene called ALLELE, from each parent. Allele is the variant form of a gene.

According to Mendel's law of dominance, for a particular trait, an allele is capable of masking the expression of another allele in a gene. The expressed allele is called the DOMINANT allele while the masked allele is called the RECESSIVE allele. Due to this, an organism can express a dominant trait even in a combined or heterozygous state i.e. different alleles.

When the two heterozygous organisms mate or are crossed, they undergo meiosis and their alleles are separated into GAMETES according to Mendel's law of segregation. For example; an organism with genotype (genetic make-up) Aa will produce gametes with A and a alleles.

Note that, a recessive trait can only be expressed in a homozygous state i.e. same allele. Hence, the two heterozygous organisms will produce gametes containing the recessive allele, which will likely combine to produce a recessive phenotype or trait.

Some orchids produce two types of flowers, one with only anthers and the other with only carpels. And on some orchids like this,

aliina [53]

Answer:

The Orchids is the diversified structures of flowers, in fact, they have unique feature. Even with the pollination, they have several mechanisms of pollination. Few of them include:

1. Few orchids have self-fertilization where the anther converts from solid-state to a liquid state without any aid of an external pollinating agent.

2. In others, self-pollination occurs, when the caudicles dry the pollen fall on the stigma.

3. This happens through an external pollinator resulting in a diversity of species.

4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.

5. These types depend on ants and other insects to get pollinated.

6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.
