how are plants different from algae?

The main difference between the two is in their complexity. Algae are simple organisms, sometimes unicellular, and even the largest types are relatively simple in structure. True plants on the other hand, are quite complex, with many specialized structures, even in the smallest types.

Algae and plants are like humans as they need food, nutrients and a good environ- ment to grow and survive. Algae make their own energy or food from the sun but they also need water, correct temperature and nutrients to grow. Algae live in water or damp environments.

To further confuse matters, some organisms with the name "moss," such as Irish moss, are in fact types of algae. However, true moss and algae are two distinct species with different characteristics. Mosses include 12,000 separate species, while algae are a group of organisms.

Alga is singular form and Algae is plural. ... Algae are the name given to a large group of oxygenic, phototrophic, eukaryotic microorganisms. Algae have a nucleus. The differences between plants and algae, many algal species are closely related to plants, but the algae are very diverse.

Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water, especially in plankton.

The cyanobacteria are also called the blue-green algae. ... Some of the cyanobacteria can be heterotrophs as well. The main difference between green algae and cyanobacteria is that green algae contain chloroplasts whereas cyanobacteria do not contain chloroplasts in their cells.

One of the main differences between plants and fungi is that fungi have chitin as a component of their cell walls instead of cellulose. Both chitin and cellulose are comprised of polysaccharide chains. ... Another contrast between plants and fungi is the presence of chlorophyll in plants and not in fungi.

The main difference between crop and plant is that plants are multicellular photosynthetic eukaryotic life-forms belonging to kingdom Plantae while crops are plants grown in large quantities for food or other commercial purposes. All crops are plants, but not all plants are crops.

Macro algae are multicellular marine algae which form a real plant. ... Micro algae are different. They are one cell algae. Spirulina, Chlorella or also blue green algae are very popular in this variety.

Plants are generally non-motile, eukaryotic, multicellular organisms (except some species of algae) and have a specific organelle in their cells called chloroplasts.

Algae can either be unicellular and multi-cellular while plants are multi-cellular organisms. 2. Algae typically live underwater while plants thrive on land. ... They don't have structures such as connective tissues, leaves, stems and roots unlike plants.

While algae contain chlorophyll (like plants), they do not have these specialized structures 8. Algae are sometimes considered protists, while other times they are classified as plants or choromists. Phytoplankton are made up of single-celled algae and cyanobacteria.

The first difference is that plant cells have an organelle called chloroplast. ... Animal cells are smaller than plant cells and have a membrane around them that is flexible and allows molecules, gases and nutrients to pass into the cell. Plant cells are larger and in addition to a membrane they have a rigid cell wall.

', 'Plant growth is indeterminate and adapted to gather diffuse resources. ... ', 'Shoots consist of simple repeated units exhibiting serial homology. ... ', 'New tissues and organs are formed at meristems.']

Algae are morphologically simple, chlorophyll-containing organisms that range from microscopic and unicellular (single-celled) to very large and multicellular. The algal body is relatively undifferentiated and there are no true roots or leaves.

All the seaweed species are autotrophic, whereas some algal species rely on other external food materials. Algae inhabit both freshwater and marine waters, while seaweeds inhabit only seawaters. Marine algae can distribute over shallow as well as deep waters, while seaweeds mostly inhabit shallow waters.

All algae contain chlorophyll but most lack leaves, roots, vascular tissue, and stems. They play a vital role in aquatic ecosystems by forming the energy base of the food web for all aquatic organisms. As autotrophic organisms, algae convert water and carbon dioxide to sugar through the process of photosynthesis.
