Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.
Answer:
A plant cell.
Explanation:
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. <u>This happens because plant cells, besides the membrane, are surrounded by a </u><u>cell wall</u><u>, which is rigid and gives the cell this form</u>.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. <u>The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the </u><u>chloroplast this distinctive green color. </u>
