SNC2D Biology: Cells, Tissues and Living Systems Plant and Animal Cell Parts (Science Perspectives 10, Nelson: pp. 29-32) Plant cells are characterized by a thick _____________ and small bodies within the cytoplasm called _________________, which give the green colour to the plants. These tiny structures are the primary food factory for all living things on Earth. ______________________ within the chloroplast is also responsible for producing the oxygen in the air you breathe. Both animal and plant cells have some similar structural elements. Animal and plant cells have a ________ ________________ that surrounds the cell. This allows for the cell to exert control, in most cases, over what can penetrate the cell and what cannot. Cell Membrane • The cell is surrounded by a flexible _________________ cell membrane. • The function of the cell membrane is both to ___________ the cell and to allow some __________________ to enter while keeping others out. • Because of this ability, the cell membrane is called a “________________________________.” Nucleus • • The nucleus is directs all of the cell's activities. It contains the ______ • The nucleus is separated from the rest of the cell by the ___________________. Mitochondria • The mitochondria is sometimes referred to as the _____________ of the cell. • Mitochondria are largely responsible for providing the cell with ___________ from glucose (sugar) through a process called ____________________________. SNC2D Biology: Cells, Tissues and Living Systems Endoplasmic Reticulum • The endoplasmic reticulum is a three-dimensional network of branching ___________ and ________________. • It extends throughout the cytoplasm from the _____________________. • These fluid-filled tubes transport materials, such as ____________ through the cell. Ribosomes • Found on the _______________________________ or ________ in the cytoplasm. • ___________ are made in this organelle. Golgi Bodies/Apparatus • Golgi bodies ___________ and ____________materials to be removed from the cell. • They also make and secrete _________. • Cells that secrete a lot of mucus, such as cells lining the ____________, have many Golgi bodies. Cytoplasm • All the _______________ inside the cell are _______________in the cytoplasm. • The cytoplasm is mostly _________, but it also contains many other __________________ that the cell stores until they are needed. • Many ____________________ take place within the cytoplasm. SNC2D Biology: Cells, Tissues and Living Systems Cell Parts Found only in Plants Chloroplasts • Contain ________________ and give leaves their green colour. • Absorb light energy which is used in ________________ Carbon dioxide + water → glucose + oxygen Cell wall Just outside the ____________________ Provides __________ and _____________ from physical injury Vacuole Plants usually have _______ ________ vacuole which takes up most of the space inside the cell. When full of water, _______ ___________ keeps the cells plump which keeps the plant’s stems and leaves firm. SNC2D Biology: Cells, Tissues and Living Systems Homework: Label the cell parts (Science Perspectives 10, Nelson: pp. 29-32) Complete the following table, by writing “yes” or “no” and any additional notes as needed.
