why don't animal cells have chloroplasts?

Question

HINT: how do animals get energy?

Answer 1

Animals don't get their energy from the sun via photosynthesis like plants. They break down their food and turn it into energy.

Answer 2

Do Animal Cells Have Chloroplasts

Answer 3

No, animal cells do not have chloroplasts in them. Only plant cells do. The only thing that would make it a little bit different is with animal like algae, which might contain some chloroplasts, but other than that, it is unlikely.

Answer 4

Animals do not perform photosynthesis. Thats why only plant cells have em, chloroplasts are sites for photosynthesis.

Answer 5

well according to the laws of the plant and animal kingdom, animals are naturally heterotrophs (they eat food orally) plants obviously do not have mouths or tongues so the are autotrophs (they make their own food). therefore they need an alternative to eating so they have chloroplast. they energy from the sun is concentrated to create glucose (sugar) this is the plants form of food. it is a process called photosynthesis.

Answer 6

because they don't need them to get energy. plants use chloroplasts during photosynthesis but animals eat in some way

Answer 7

Chloroplasts are only found in plants. They even have the same prefixes! CHLOROplasts and CHLOROphyll. Animals don't have them because...well I don't really remember off hand, but animals get energy from carbohydrates and food and water.

Answer 8

Cholorplasts are in plants, not animals. Animals get their energy eating plants or other animals.

Answer 9

Cells vary widely in form and function, even within the same organism. The human body, for example, is made up of about two hundred different types of specialized cells, ranging from foot-long nerve cells to tiny, disk-shaped blood cells. At first glance these cells appear to have little in common other than the body or body part that houses them. For all their differences, though, different types of specialized cells have a lot in common. Even plant and animal cells have far more structural similarities than they have differences.

Plant and animal cells have nearly all of the most important cell structures in common. For example, both plant and animal cells have a nucleus, which contains the cell's genetic material, or DNA. Plant and animal cells also have some of the same organelles floating in the cytoplasm, the fluid-filled region between the cell membrane and the nucleus: Mitochondria, the cell's "powerhouses," create energy through the process of aerobic respiration; ribosomes are responsible for synthesizing proteins; the endoplasmic reticulum stores and transports proteins and other compounds within and outside the cell; Golgi bodies transform proteins into more complex molecules; and lysosomes contain as many as 40 different enzymes used to break down large molecules. Indeed, even under a microscope it is difficult to tell apart many plant organelles from the same organelles found in animals.

Despite all their similarities, plant cells and animal cells differ in two important ways. First, plant cells have structures called chloroplasts, and animal cells don't. Chloroplasts are the structures that give leaves their green color and, more importantly, allow plants to acquire their energy from the sun rather than from food, the primary source of energy for animals. Like mitochondria, chloroplasts convert energy from one form to another. However, this process, called photosynthesis, is in many ways the opposite of the mitochondria's aerobic respiration process. In aerobic respiration, food molecules are combined with oxygen to produce energy and carbon dioxide. In photosynthesis, chloroplasts use energy from the sun to convert carbon dioxide and water into food molecules like sugars and other carbohydrates.

All cells have a cell membrane, a structural layer that gives the cell shape, while allowing molecules of various types to pass into and out of the cell. Unlike animal cells, however, plant cells have a cell wall that surrounds the entire cell, including the membrane. The cell wall provides plant cells with a protective covering and gives the plant the rigidity it needs in order to stand up even under pressure from wind, rain, and snow. This wall is made of cellulose and is intricately cross-linked with fibers of other carbohydrate molecules. This structural pattern also allows each cell to withstand the increased internal pressure from osmosis, when the plant absorbs water.

Answer 10

No animal cells do not have chloroplasts.
Animals get theier energy from plants, carnivores get their energy by eating herbivores and so on.
