Biology Activity 1

The document outlines an activity to compare and contrast plant and animal cells. The objectives are to define "cell", label parts of plant and animal cells, take photos of each, and write about their significance. Materials like onions, toothpicks, and microscopes are listed. The procedure will involve examining plant and animal cells under a microscope and answering questions. Key differences noted are that plant cells have cell walls and chloroplasts while animal cells do not. Both share structures like the nucleus, membrane, and organelles. In conclusion, the activity helped observe differences between these two important cell types.

Cell Wall: Plant cells have a rigid cell wall made of cellulose, while animal cells lack a cell wall.

Chloroplasts: Plant cells contain chloroplasts for photosynthesis, which are absent in animal cells.
Vacuole: Plant cells have a large central vacuole for storing water and nutrients, while animal cells have
smaller or multiple vacuoles with various functions.

Lysosomes: Lysosomes are rarely found in plant cells but are common in animal cells.

Centrioles: Animal cells typically have centrioles, which are absent in plant cells.

Cilia and Flagella: While some animal cells have cilia and flagella for locomotion, these structures are
rarely found in plant cells.

Storage Compounds: Plant cells store energy in the form of starch, while animal cells store energy as
glycogen.

Shape: Plant cells often have a fixed shape due to the presence of the cell wall, while animal cells have a
more flexible and round or irregular shape.

Despite these differences, both plant and animal cells share fundamental structures such as the nucleus,
cell membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, mitochondria, and more, which are
essential for their basic functions and survival.

In conclusion, the plant cell and animal cell experiment helped us see the differences between these two
types of cells. Plant cells have cell walls and chloroplasts for photosynthesis, while animal cells do not.
Understanding these distinctions is important for biology and has real-world applications in areas like
agriculture and medicine. It's fascinating to learn how these tiny cells play a big role in the living world
around us.

In conclusion, studying plant cells and animal cells has shown us that even though they're both tiny, they
have important differences. Plant cells have cell walls and chloroplasts, while animal cells don't. These
differences help us understand how plants and animals work and are essential for many aspects of
science and our daily lives. It's incredible how such small things can have such a big impact!
In conclusion, our simple experimental investigation into plant and animal cell activity has provided
valuable insights into the fundamental differences and similarities between these two types of cells.
Through the use of basic microscopy techniques and observations, we were able to witness various
cellular processes in action.

One key observation was that both plant and animal cells exhibit essential life processes, such as cell
division and organelle activity. These processes are crucial for the growth, development, and
maintenance of living organisms, regardless of their classification as plant or animal.
