What does a plant need to survive? How are plant and animal needs different? The same? Are plants and animals both living things? Discuss how you could tell. Details Activity Length 30 mins. In this activity, students sort samples into living or non-living things.
Living components of a forest include: plants e. Objectives Describe the basic needs of living things Materials Pictures or samples of living and non-living forest components Key Questions What does an animal need to survive?
What To Do Divide the class into small groups. Hand out a selection pictures or samples of non-living and living things to each group. Water is one of the building blocks of life, but it cannot reproduce. It cannot grow or develop, and it does not die. If you were to go into a forest, you would be able to observe both living things and nonliving things. In a forest, you may see many living things, such as trees, animals, bacteria or fungus.
You would also see nonliving things, such as water or rain , sunlight, oxygen and rocks. Water is not the only thing that's often mistaken for being a living thing or vice versa. For example, in the reverse, some may believe that a seed is not a living thing.
Of course, a seed may not yield fruit without air, water or soil, but it's still a living thing. It simply needs nutrients to grow. Similarly, a leaf that falls to the ground is considered dead; yet, it's still a living thing. Wind, like water, often gets mistaken for being a living thing because of its characteristics, such as "angry," "gentle" or "strong.
Some things you could ask yourself would be:. Most living things share the above characteristics, so if the answer is "no" to these questions, then it likely is a nonliving thing. Like wind, water is often easily mistaken for a living thing due to its characteristics. Water is especially confusing since every living thing needs it to survive. However, think about how people describe water, such as a "strong" undertow, a "weak" trickle or a "heavy" rain.
A living thing, biologically speaking, encompasses both extant and extinct species. The basic similarity between living and non-living things is that both of them pertain to that which exists. A thing is a distinct entity, being, matter, or object. A thing may be classified based on whether or not life is exhibited. A living thing is one that possesses or exhibits life as opposed to a non-living thing that lacks life.
A non-living thing is not organized into cell s ; a living thing is. Although both non-living and living things are essentially made up of molecules of elements and compounds, a living thing would be made up of biomolecules organized into structures of a cell.
The cell is the fundamental biological unit of a living thing. It carries out various cellular processes in an orchestrated, systematized manner. It is responsible for maintaining the living state of the organism by performing various metabolic processes, e.
The cell is made up of protoplasm surrounded by a plasma membrane. Several cytoplasmic structures are suspended in the cytosol. One of the most prominent cytoplasmic structures is the nucleus. Based on the presence of membrane-bound organelles, such as nucleus, living things may be classified into either prokaryotes or eukaryotes. Membrane-bound organelles are lacking in prokaryotes whereas in eukaryotes they are present.
A non-living thing does not grow the same way a living thing does. Some non-living things seem to display growth, however, the growth occurs by accretion rather than by metabolic reactions. In living things, growth at the cellular level is manifested by an increase in the number of cells or by an increase in the cell size.
The cells grow in number through cell division e. As for the increase in cell size, it is attributed often to an increase in the cytoplasmic mass. Some organisms have the capacity to regrow lost parts. Plants, for instance, can grow new shoots at the site where it has been cut as long as the meristematic tissue remains intact. Salamanders can regenerate new eyes or new limbs. Humans have a rather limited regeneration capacity. They can regenerate skin and certain parts of the liver.
Non-living things are non-motile whereas most living things are motile. Non-living things may seem to move. However, the movement is due to an external influence. Many living things can move around spontaneously. Animals have locomotory organs that enable movement. They use them to move, especially in response to stimuli. For instance, animals escape by running away from their predators when they see them. Animals also move with the intent to forage, look for more suitable habitat, or seek a potential mate.
While most animals can move at will, most plants cannot. Although plants are not as motile as most animals, they are still regarded as living because they manifest many other characteristics of life.
Non-living things cannot naturally create copies of their own kind; living things can, by reproduction.
