Animals and plants need oxygen. When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere.

Plants and animals are the two primary systems in the biosphere’s cycle of life, with plants “exhaling” oxygen through photosynthesis and animals inhaling oxygen through the lungs and exhaling carbon dioxide as a byproduct. Plants require carbon dioxide to live and flourish with their end-product again becoming oxygen.

PLANTS are permeated by the same gases that make up the atmosphere surrounding them: oxygen, carbon dioxide and nitrogen.

Answer: All living things must produce offspring like themselves in order for their species to survive. This is the process known as reproduction. Plants produce seeds that give rise to new plants of the same species. Animals lay eggs or have babies.

Animal cells do not have cell walls and have different structures than plant cells Plants have either no or very basic ability to sense. Animals have a much more highly developed sensory and nervous system. Plants are autotrophic Animals are heterotrophic.

Major structural differences between a plant and an animal cell include:

• Plant cells have a cell wall, but animals cells do not.
• Plant cells have chloroplasts, but animal cells do not.
• Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.

A plant cell is surrounded by rigid cell wall whereas animal cell does not have cell wall. Presence of a large vacuole in plant cell, which is small in animal cell. Plant cells are larger than animal cells. Plant cells have plastids whereas animal cells do not have plastids.

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

Plant cells have cell walls, one large vacuole per cell, and chloroplasts, while animal cells will have a cell membrane only and several smaller vacuoles. Animal cells also have a centriole, which is not found in most plant cells.

Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

Plants and animals are living things. They feed, respire, excrete, grow, move, reproduce and are sensitive to their environment. Animals and plants need food for energy but they feed in different ways. Animals eat plants and other animals, but plants make their own food.

Plants have chloroplasts while animalsdon’t, and plants have cellulose cell walls while animals don’t have anything more than cell membranes around their cells. Etc. The similaritiesinclude eukaryotic cells and all that that entails — cell nuclei, chromosomes, an endomembrane system, mitochondria, etc.

1) They both are living organisms. 2) They make/catch their own food. 3) They both have charecters of living things. 4) They are made up of cells.

Background Information: Even though plants look different, all plants have three things in common: They are made up of more than one cell; they are able to make their own food; and they are green. Plants are different from animals in two important ways. They cannot move about and most are able to make their own food.

All cells are surrounded by a membrane and contain genetic material but otherwise are structurally diverse. All cells have structural and functional similarities. Structures shared by all cells include a cell membrane, an aqueous cytosol, ribosomes, and genetic material (DNA).

Dogs are slightly different in that they also enjoy the companionship of their fellow pooches as well as their owners whereas cats tend to enjoy their own company in the same way they appreciate the bond that comes with being domesticated.

Although each individual animal and plant species has its own specific life cycle, all life cycles are the same in that they begin with birth and end with death. Growth and reproduction are two of the central components of the life cycles of plants and animals.

3-LS 1-1 Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.

Birth, growth, reproduction and death represent the four stages of the life cycle of all animals. Although these stages are common to all animals, they vary significantly among species. For instance, while insects, birds and reptiles are born from an egg, mammals develop as embryos inside the mothers’ bodies.

Most classes of animals, including fish, mammals, reptiles, and birds, have fairly simple life cycles. First they are born, either alive from their mother or hatched from eggs. Then they grow and develop into adults. These animals undergo a metamorphosis (a significant change in their physical structure or habits).

All living things (organisms) have a life cycle. They are born, grow up, reproduce and die. Different groups of organisms (species) have different kinds of life cycles.

Animals that Grow Up (Simple Life Cycle): These animals have three stages — before birth, young and adult. The young are typically similar to the parent, just smaller. The young slowly “grow” to become adults.

The life cycle of an organism refers to the sequence of developmental stages that it passes through on its way to adulthood. Surprisingly, only about 3% of all animal species give birth to live young as part of their life cycle. Most animals lay eggs.

There are three different plant life cycles: haploid (1n), diploid (2n), and the more common haploid-diploid (1n-2n). A haploid organism consists of a multicellular structure of cells that contain only one set of chromosomes, whereas, a diploid organism’s multicellular stage contains two sets of chromosomes.

The gametic life cycle is the reproductive cycle found in animals and some protistans. During the gametic life cycle a reproductive cell produces haploid gametes (sex cells such as egg and sperm) that combine to produce a zygote.
