Plant cells have a cell wall, plastids, such as chloroplasts which contain the green photosynthetic pigment chlorophyll in green plants, a vacuole which is an organelle(cellular subunit) that contains water allowing the plant to maintain turgidity(turgor pressure allows plants to have rigid structure when the water pushes against the vacoule containing water.) An example of turgidity/turgor pressure is soaking lettuce leaves in water to maintain its crispness. Plants have stomata in their cells, which allow leaves to let water enter and exit the cell. If you have ever felt a mist coming from a tree you are sitting under on a hot summer day, then you have felt water coming from the tree's leaves. This phenomenon is called transpiration.
Most textbooks demonstrate a typical model of a plant cell. These models are like composite sketches of a suspect made by sketch artists drawing pictures of the suspect from eyewitness accounts. The picture is not a complete representation of the suspect because it will not have all of their features.
So, as you study the plant versus animal cells find other representations of different types of plant cells, e.g. leaf cells, onion epidermal cells, etc..in addition, different representations of animal cells such as human cheek cells, red blood cells, etc... should be helpful as study tools.
