BIOLOGY 1 CELLS AND TISSUES MODULE 4 REVIEW OF PREVIOUS LESSON FILL IN THE BLANKS 1. Prokaryotic and Eukaryotic cells can be distinguished by the presence or absence of the ________________. NUCLEUS FILL IN THE BLANKS 2. The energy producing organelle found both in animal cells and plant cells is known as the mitochondria _______________. FILL IN THE BLANKS 3. The main organelle in the cell that produces protein is known as the _________. ribosome FILL IN THE BLANKS 4. Prokaryotes can hold on to handrails and doorknobs because of their bristle Fimbriae like appendages call______________. FILL IN THE BLANKS 5. Plasmid is a structure that is mostly bacteria found in ______________. LEARNING COMPETENCY AND OBJECTIVES LEARNING COMPETENCY At the end of this module the students should be able classify different cell types (of plant/animal tissues) and specify the functions of each. (STEM_BIO11/12-Ia-c-4). LEARNING OBJECTIVES Specifically after this lesson the learners should be able to 1. differentiate parenchyma, sclerenchyma, and collenchyma cells of plants. 2. describe and explain the function of dermal, ground, and vascular tissue in plants. LEARNING OBJECTIVES 3. identify the different animal cells (blood cell, nerve cell, bone cell, etc) 4. describe and explain the function of the 4 major types of animal tissues. LET’S CHECK WHAT YOU KNOW… FILL IN THE BLANKS 1. A group of cells that have the same structure and function is called a ____________. Tissue or organ FILL IN THE BLANKS 1. A group of cells that have the same structure and function is Tissue called a ____________. or organ FILL IN THE BLANKS 2. Xylem and phloem is an example of __________tissue. plant or animal FILL IN THE BLANKS 2. Xylem and phloem is an example plant of __________tissue. or animal FILL IN THE BLANKS 3. Nerve is an example of __________tissue. plant or animal FILL IN THE BLANKS 3. Nerve is an example of animal __________tissue. plant or HISTOLOGY PLANT TISSUES HISTOLOGY Is the study of cell and tissues PLANT TISSUES DIVIDE TISSUE MERISTEMATIC PERMANENT FUNCTION XYLEM 1. When large number of specialized cells come together, they form a _____________ DIVIDE TISSUE MERISTEMATIC PERMANENT FUNCTION XYLEM 2. the two basic types of plant tissue are ____________ and __________. DIVIDE TISSUE MERISTEMATIC PERMANENT FUNCTION XYLEM 3. Meristematic tissue help in the growth of plant because they have the ability to _______________. DIVIDE TISSUE MERISTEMATIC PERMANENT FUNCTION XYLEM 4. simple permanent tissue is called simple because it is composed of similar types of cells that have a common origin and ____________ DIVIDE TISSUE MERISTEMATIC PERMANENT FUNCTION XYLEM 5. the complex tissue that transports water and mineral in plants is called ______________. Plant tissues Meristem Permanent Based on origin Simple Complex Based on position Ground Dermal Vascular Based on function 1. Parenchyma 1. Xylem 1. Epidermis 2. Collenchyma 2. Dermis 2. Phloem 3. Sclerenchyma MERISTEMS VS PERMANENT TISSUE MERISTEMS Young and immature cells MERISTEMS Divide continuously MERISTEMS Has the ability to 1. Enlarge and stretch 2. Differentiate into other cells MERISTEMS Increase the length and girth of the plant MERISTEMS Building blocks of specialized plant structures. (buds of leaves and flowers, tips of roots and shoots) PERMANENT TISSUES Mature cells PERMANENT TISSUES Non-dividing cells PERMANENT TISSUES Arise from meristems PERMANENT TISSUES Main functions include the conduction of water, minerals, and nutrition. Provides support, protection, and helps in photosynthesis. MERISTEMS MERISTEM BASE ON ORIGIN MERISTEM BASED ON ORIGIN 1. Primordial M. 2. Primary. 3. Secondary M. 1.PRIMORDIAL MERISTEM Earliest meristematic tissue Embryonic origin 2.PRIMARY MERISTEM Three kinds of primary meristems. Protoderm - develops into epidermis Procambium - develops into primary xylem and phloem Ground meristem - develops into the cortex and the pith. 3.SECONDARY MERISTEM It is also called a lateral meristem. There are two types of lateral meristem. 1. vascular cambium - produces secondary xylem and secondary phloem. 2. cork cambium - produces the periderm which replaces the epidermis. MERISTEM BASE ON LOCATION MERISTEM BASED ON LOCATION 1. Apical M. 2. Intercalary M. 3. Lateral M. 1. APICAL MERISTEM Located in the tips of shoots and roots Increase height of the plants. 1. APICAL MERISTEM 2. INTERCALARY MERISTEM Located in the leaves and internodes Increase the length of the internode 2. INTERCALARY MERISTEM 3. LATERAL MERISTEM Located in the stems and roots on the lateral side. Increases the thickness of the plant Vascular and cork cambium MERISTEM BASE ON FUNCTION MERISTEM BASED ON FUNCTION 1. Protoderm 2. Procambium 3. Ground Meristem PROTODERM is the outer Meristematic Tissue that protects from injuries. PROCAMBIUM is the inner Meristematic Tissue that helps in the transportation of nutrients and water. GROUND MERISTEM helps in the development of ground tissue, endodermis, pericycle and cortex.

Vascular Dermal Ground Vascular Dermal Vascular Ground Dermal Vascular Ground Vascular Ground Dermal DERMAL TISSUE DERMAL TISSUE 1. Epidermis 2. Periderm EPIDERMIS A single layer of closely packed parenchymatous cells. EPIDERMIS Contains… 1. Stomata 2. Cuticle STOMATA regulate water intake and help in gaseous exchange. CUTICLE Reduces water loss through the epidermis. PERIDERM Multilayered and consists of nonliving cells that cover the outside of stems and roots to protect the plant. PERIDERM Replaces epidermis in plants that undergo secondary growth GROUN D TISSUE 3 TYPES OF GROUND TISSUE Living cells Oval or round shape Thin walled 3 TYPES OF GROUND TISSUE Small nucleus Have vacuole Found in all parts of the plant 3 TYPES OF GROUND TISSUE Involved in photosynthesis, secretion, food storage, and other activities of plant life 3 TYPES OF GROUND TISSUE Living cells Elongated/ long cells Thick- walled cells Flexible 3 TYPES OF GROUND TISSUE Found mostly in the cortex of stems and leaves Primary supporting tissues of herbaceous plants 3 TYPES OF SIMPLE/ GROUND TISSUE Dead cells Thick- walled Various shapes Rigid and non stretchable 3 TYPES OF SIMPLE/ GROUND TISSUE Found in non growing parts (bark or mature stems) Provide mechanical support and rigidity to the plan VASCULAR TISSUE 2 VASCULAR TISSUE XYLEM Hollow vessel Non living cells 2 parts: Tracheid and vessel element XYLEM Transports water and minerals from roots to leaves.
