Solution 6: (a) Green plants are called autotrophs since they synthesise their own food.

Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

Green plants are called producers because they make their own food out of water and carbon dioxide in the presence of sunlight.

A saprophyte or saprotroph is an organism which gets its energy from dead and decaying organic matter. Some fungi are parasites on living organisms, but most are saprophytes. Many bacteria and protozoa are also saprophytes. Most dead organic matter is eventually broken down and used by bacteria and fungi.

All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic. In contrast, green plants, red algae, brown algae, and cyanobacteria are all autotrophs, which use photosynthesis to produce their own food from sunlight.

No, all plants are not autotrophic. Some of the non-green plants such as dodder plants obtain their food from other plants and these plants are heterotrophic plants.

All plants are not autotrophs. The plants usually have a green pigment called Chlorophyll which has Chloroplasts. These trap the energy from the sun. ↪So , only those plants that have chlorophyll are autotrophs.

All green plants can prepare their own food. Most animals are autotrophs.. (3) Carbon dioxide is not required for photosynthes. 4 Oxygen is liberated during photosynthesis.

All plants or the autotrophs use energy from the sun to convert carbon dioxide from the air and water from the soil in to glucose, which gives plant energy and is also utilized in the synthesis of cellulose by the plants which is used to grow and build plant cell wall.

Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers.

Cells in green algae divide along cell plates called phragmoplasts and their cell walls are layered with cellulose in the same manner as the cell walls of embryophytes. Consequently, land plants (embryophytes) and closely-related green algae ( Charophyta ) are now part of a new monophyletic group called Streptophyta.

One difference between green algae and plants is that green algae do not have a cuticle. Because they live in the water so they don’t need a cuticle like plants to prevent water loss.

Green algae have chloroplasts that contain chlorophyll a and b, giving them a bright green color, as well as the accessory pigments beta carotene (red-orange) and xanthophylls (yellow) in stacked thylakoids. The cell walls of green algae usually contain cellulose, and they store carbohydrate in the form of starch.

Land plants are monophyletic.

The “green algae” is a paraphyletic group because it excludes the Plantae. Like the plants, the green algae contain two forms of chlorophyll, which they use to capture light energy to fuel the manufacture of sugars, but unlike plants they are primarily aquatic.

plant clades

Thus, many plant species are likely to be paraphyletic, and predictably a species classification based on the criterion of monophyly is unlikely to be an effective tool for describing and ordering biological diversity.

In the traditional taxonomy of vertebrates, where fish are a separate class from the classes of terrestrial vertebrates, the class of fish is paraphyletic, since the terrestrial vertebrates are descended from a type of fish.

: of, relating to, or being a taxonomic group that does not include all descendants of a common ancestor.

: a character or trait that is shared by two or more taxonomic groups and is derived through evolution from a common ancestral form.

Polyphyly is a term in cladistics. It describes a group of organisms whose last common ancestor is not a member of the group. Another way of expressing this is to say that polyphyly includes groups some members of which are descended from ancestral populations.

According to the tree of life, members of a common ancestral group that stop interbreeding form separate stems or sister taxons. For example, chimpanzees and human beings are sister taxa. There are three main designations of phyletic, or race and tribe, groupings: monophyletic, paraphyletic, and polyphyletic.

The arrangement of the members of a polyphyletic group is called a polyphyly /ˈpɒlɪˌfaɪli/. Alternatively, polyphyletic is simply used to describe a group whose members come from multiple ancestral sources, regardless of similarity of characteristics.

A polyphyletic taxon is defined as one that does not include the common ancestor of all members of the taxon [as in (b)]. Note that these latter groups are defined by ‘absence’ characters, and that although redwood trees are jawless and toothless, they are not included in those taxa.
