2.

The basic plant cell has a similar construction to the animal cell, but does not ... It does have additional structures, a rigid cell wall, central vacuole, ... namely xylem, which is involved in structural support and water conduction, ... to provide energy, particularly when light isn't available for the chloroplasts to produce energy.

3.

What structures does a plant cell have that an animal cell does not have? ... The centrosome is a region near the nucleus of animal cells that functions as a ... Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. ... Like mitochondria, chloroplasts also have their own DNA and ribosomes.

4. Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant ... Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for ...

Answer:

Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.

Explanation:

Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.

Otrada [13]

Answer:

The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.

Explanation:

The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.

In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.
