Drag each tile to the correct location.
OLEGan [10]

Answer:

Plant-like:

presence of flagella

shows the absence of cell wall, though chloroplast may be present

Animal-like:

absence of cell wall, as well as chloroplast

Fungus-like:

feeds on decaying matter

enclosed by a membrane called a pellicle

slime mold belongs in this category

Explanation:

The protists can be classified into three groups (plant-like, animal-like, fungus-like) based on the method of nutrition, movement, and mode of reproduction.

Plant-like protists have chloroplasts and trapped sunlight to form food ad energy (photosynthesis). They also have flagella used for the movement.

Example: Algae

Animal-like protists are heterotrophs that cannot make their food. They do not have chloroplast and cell wall outside the cell membrane.

Example: Protozoa

Fungus-like protists are single-cell eukaryotes that have a protective layer outside the cell membrane called pellicle. They feed on decaying organic matter.

Example: Slime mold and water mold

Help me solve for 9 pleaseeee
DaniilM [7]

Answer:

<em>The correct option is D) the rate of photosynthesis increases and then levels off.</em>

Explanation:

Photosynthesis can be described as the process by which plants make their own food from carbon dioxide and water by using light energy from the Sun. Oxygen is produced as a by-product of this reaction.

As we increase the intensity of light, the rate of photosynthesis also increases. But after a certain time, the reaction rate will level off as there might be enough food produced or the light energy might have caused the temperature to rise which would have caused the enzymes to get denatured.
