plant progject_los
Plants have the ability to detect light and grow towards it due to different elongation rates in their stems. The students hypothesized that bean seeds planted horizontally and vertically would grow differently, with water causing horizontal growth and light causing vertical growth. They designed an experiment to test this by planting bean seeds and observing their direction of growth in response to light and water.
Hebrew Leaders
Abraham was considered the founder of Judaism and the "Father of the Hebrews". Moses was a Hebrew baby who was set adrift in the Nile River but was found and raised by the daughter of the Pharaoh. As an adult, Moses led the Hebrews out of slavery in Egypt after God commanded him to tell Pharaoh to free them. David was a young boy who killed the giant Goliath, allowing the Hebrews to retake their promised land. He later became king and established Jerusalem as their holy city. Solomon built the first Jewish temple there to house the Ark of the Covenant after succeeding his father, King David.

Fruits develop from pistils or clusters of flowers.
Parts of plants
The document discusses the parts of a plant and how plants grow from seeds. It notes that roots take in water and nutrients from the soil, stems hold up the plant and move water and nutrients, and leaves use sunlight, air, water and nutrients to make food. Flowers make fruits containing seeds. Seeds are scattered by planting, animals, water and wind and can germinate into seedlings when they have sunlight, air, water and nutrients.
PLANTS IN THE SURROUNDINGS - Copy.pptx
Plants provide humans with many essential things like food, clothing, timber, and medicines. They come in many varieties including trees, shrubs, herbs, climbers, and aquatic plants. Plants have two main systems - the root system which absorbs water and minerals from the soil, and the shoot system including stems, leaves, flowers, and fruits. Leaves perform photosynthesis to produce food, while flowers help reproduction and attract pollinators. Fruits contain seeds which germinate into new plants under suitable conditions like moisture, warmth and sunlight. Proper care of plants involves providing them space, water, and avoiding damage.

Stems transport water and nutrients and support other structures. Roots absorb water and nutrients and anchor the plant.
Al blog plants
This document discusses the parts of a plant and the plant life cycle. It explains that plants need sunlight, air, water and nutrients to grow. The main parts of a plant are the roots, which take in water and nutrients, the stem, which holds up the plant and transports water and nutrients, and leaves, which use sunlight to make food. Flowers produce fruits containing seeds. Seeds are scattered by wind, water, animals or planting. When conditions are right, seeds germinate by sprouting roots and a stem to begin the life cycle again.

Taxonomy webquest
Carl Linnaeus laid the foundation for modern taxonomy but did not work alone. While studying to become a doctor, Linnaeus developed an interest in collecting plants, which led him to create a classification system. His book "Systema Naturae" documented this system, though he relied on collaboration with students and peers, demonstrating that scientific discovery is cooperative. Linnaeus' plant classifications were based on characteristics like flower parts, but modern taxonomy uses additional genetic and anatomical traits.
The Great Leaders
The document summarizes the contributions of four important Jewish religious leaders: Abraham, Moses, David, and Solomon. It describes how Abraham introduced monotheism and Judaism, Moses led the Hebrews out of slavery in Egypt and received the Ten Commandments, David united Israel and made Jerusalem its capital, and Solomon built the first Jewish temple in Jerusalem.
The Four Great Hebrew Leaders
Abraham was the first patriarch of Judaism who was willing to sacrifice his son Isaac at God's command, establishing his faith and God's covenant to make his descendants numerous. Moses led the Hebrews out of slavery in Egypt through the ten plagues and parting of the Red Sea. David united Israelite tribes and made Jerusalem the capital. Solomon built the first Jewish temple there to house the Ark of the Covenant. Together these four leaders were foundational to Jewish faith and society.

- 4. Leaves • The Job for the leaves is to absorb sunlight so photosynthesis can occur to make food for the plant • They also let water, carbon dioxide, and oxygen in and out
- 5. Stems • The stems help the plant by carrying water and nutrients taken up by the roots to the leaves
- 6. Flowers • The flowers are important for making seeds • They also make new plants with the process of fertilization
- 7. Roots • The roots help by supporting the plant by anchoring the plant and absorbing nutrients and water needed for the the plant to survive
- 8. Fruits • The fruit is the ripened ovary of the plant, containing the seeds • The fruit also provides humans and animals with food
- 9. Identifying Plants plants can be identified in many ways! Here are some ways • They can be identified by there leaves, some plants have leaves that are different shapes and sizes • Some can even be identified by there flowers, the petals can be different colors like red, blue and much more
