6. "Investigation of the structure of Angiosperm plants". STEPS OF THE WORK Examine the external appearance of the plant based on the illustrations of "Structure of the rosehip". Note the structural features according to the following plan: Life form (grass, shrub, tree). This can be determined because the plant has . What is a special feature of the stem of the rosehip? On the stem there are. Stem character (upright, twining, creeping). The flower of the rosehip has a corolla made of petals. Leaves (simple or compound), venation: (reticulate or arcuate). Leaf arrangement (alternate, opposite, whorled). Observe

или обратнополустоячая позиция): The leaves of the rosehip are. Traces of past growth: There are marks left on the stem of the rosehip, indicating the location of the. Root system (taproot, fibrous roots): The rosehip has a root system. Once you have examined the external appearance of the plant and noted down the structural features, you can move on to the next step of the investigation.

The next step is to dissect the plant and examine its internal structure. This can be done by carefully cutting open the stem, leaf, and flower of the rosehip using a scalpel or scissors. Take note of the following observations:

Stem structure: In the stem, you will notice the presence of. This is an important structural feature of the rosehip"s stem. Additionally, you may observe the arrangement of. This structural feature helps the stem in performing its functions.

Leaf structure: Examine the internal structure of the leaf. Notice the presence of. This is a key feature of the rosehip"s leaves. You may also observe the arrangement of. This structural feature aids in the process of.

Flower structure: Carefully dissect the flower and observe its internal structure. Take note of the presence of. This is a distinct feature of the rosehip"s flower. Additionally, you may observe the arrangement of. This structural feature plays a crucial role in.

Root structure: Dig up the plant and carefully wash away the soil from the root system. Observe the presence of. This is a characteristic feature of the rosehip"s root system. Additionally, you may notice the arrangement of. This structural feature helps the root system in.

Each step of the investigation provides valuable information about the structure of the rosehip plant. By examining its external appearance and dissecting it to observe its internal structure, we can gain a comprehensive understanding of the plant"s anatomy. These observations and structural features are essential for further studies and research in the field of angiosperm plants.

Remember to record all your observations and findings in a systematic and organized manner. This will help you in analyzing the data and drawing accurate conclusions about the structure of the rosehip plant. Good luck with your investigation!
